PPSC Past Papers & Solved MCQs

Foundational Concept: This question tests vocabulary, specifically the ability to identify antonyms (words with opposite meanings).

Correct Answer:

• B: Irrelevant is the correct answer. The word "germane" means relevant or pertinent to a subject under consideration. Therefore, its antonym is "irrelevant," meaning not connected or pertinent to something.

Incorrect Options:

• A: Relevant is a synonym of "germane," not an antonym.
• C: Appropriate means suitable or proper in the circumstances, which is closer to the meaning of "germane" than its opposite.
• D: Suitable is also a synonym for "appropriate" and "germane," indicating fitness or appropriateness for a particular purpose.

Foundational Concept: This question tests knowledge of famous literary quotes and their authors, particularly from English Romantic poetry.

Correct Answer:

• B: William Wordsworth is the correct answer. The famous line "The Child is father of the Man" is from William Wordsworth's poem "My Heart Leaps Up" (also known as "The Rainbow"). It suggests that the experiences and innate qualities of childhood shape the adult.

Incorrect Options:

• A: William Blake was a contemporary Romantic poet, but this quote is not attributed to him.
• C: John Keats was another prominent Romantic poet, known for his odes, but this quote is not his.
• D: Robert Frost was an American poet of the 20th century, long after Wordsworth, and this quote is not from his works.

The correct option is "asked for" because it uses the simple past tense, which is appropriate for a completed action in the past. The sentence describes an event that has already occurred.

• A: ask for is incorrect because for a singular third-person subject like 'Aslam' in the present tense, it should be 'asks for'.
• B: asked for correctly uses the past tense form of the verb 'ask', fitting the context of a past action.
• C: has is an auxiliary verb or indicates possession, not the action of requesting.
• D: have is incorrect as it does not agree with the singular subject 'Aslam' and does not convey the action of requesting.

Proper verb tense and subject-verb agreement are crucial for grammatical correctness.

The correct preposition to use with the adjective 'jealous' when referring to someone else's possessions, qualities, or success is "of". This is a standard idiomatic expression in English.

• A: on is incorrect. 'Jealous on' is not a standard English construction.
• B: of is the correct preposition. One is 'jealous of' another person's success or possessions.
• C: with is incorrect. While 'angry with' or 'pleased with' are common, 'jealous with' is not.
• D: for is incorrect. 'Jealous for' is not used in this context; 'for' typically indicates purpose or duration.

Mastering prepositional phrases is essential for accurate and natural-sounding English.

The word "Nexus" refers to a connection or series of connections linking two or more things, or a central and most important point or place. Therefore, "Connection" is its direct synonym.

• A: Connection accurately defines 'nexus' as a link or bond between elements.
• B: Isolation is an antonym, meaning separation or detachment.
• C: Sequence refers to a particular order in which related things follow each other, which is different from a central link.
• D: Separation is also an antonym, meaning the action or state of moving or being moved apart.

Understanding synonyms helps in expanding vocabulary and comprehending nuanced meanings in language.

The correct word to intensify the adjective 'weak' in this context is "very". 'Very' is used to emphasize the degree of an adjective or adverb without implying excessiveness or a negative connotation.

• A: too implies an excessive or undesirable degree (e.g., 'too weak to stand').
• B: much is typically used with uncountable nouns (e.g., 'much water') or in comparative structures (e.g., 'much weaker'). It's not used directly before a positive adjective like 'weak'.
• C: very is the appropriate intensifier for adjectives like 'weak', indicating a high degree.
• D: so can intensify, but often implies a consequence (e.g., 'so weak that he fell') or is used in specific emphatic structures. 'Very' is the most straightforward intensifier here.

Choosing the correct intensifier depends on the nuance and grammatical context.

The symbol () is commonly known as "Parenthesis". These curved brackets are used in writing to enclose supplementary material, such as an explanation, comment, or qualification, that is separate from the main text.

• A: Square bracket refers to the symbols [ ], which have different uses, often for editorial insertions or technical notation.
• B: Parenthesis is the correct term for the curved brackets ().
• C: None of these is incorrect as 'Parenthesis' is a valid option.
• D: all is incorrect as only one option correctly identifies the symbol.

Understanding punctuation marks and their correct terminology is fundamental for clear communication in written language.

Netscape Communications Corporation was a prominent American computer services company, best known for its web browser, Netscape Navigator. It was founded by James Clark and Marc Andreessen.

• A: Larry Page is incorrect; he is known as a co-founder of Google, not Netscape.
• B: James Clark is correct; he was a co-founder of Netscape.
• C: Marc Andreessen is correct; he was also a co-founder of Netscape and a key developer of the Mosaic web browser.
• D: Both B & C is the correct answer, as both James Clark and Marc Andreessen were instrumental in founding Netscape.

Knowing the key figures behind influential technology companies is important for understanding the history of computing.

An Inkjet Printer is a type of non-impact printer that creates a digital image by propelling droplets of ink onto paper. It uses a print head with numerous tiny nozzles that precisely spray microscopic ink droplets to form characters and images.

• A: Laser Printer uses toner (powdered ink) and a laser to create an electrostatic image on a drum, which then transfers the toner to paper using heat and pressure.
• B: Dot Matrix Printer is an impact printer that uses a print head to strike an ink-soaked ribbon against the paper, forming characters from a matrix of dots.
• C: Inkjet Printer accurately describes the technology of spraying ink through nozzles.
• D: Thermal Printer uses heat to produce an image on heat-sensitive paper, often used for receipts.

Understanding the different printing technologies helps in selecting the appropriate device for specific needs.

Artificial Intelligence (AI) is primarily associated with the Fifth Generation of computing. This generation, which began in the 1980s and continues today, focuses on developing computers that can understand natural language, learn, and make decisions, mimicking human intelligence.

• A: Third Generation (1964-1971) was characterized by integrated circuits and operating systems.
• B: Fourth Generation (1971-1985) saw the development of microprocessors, personal computers, and networking.
• C: Fifth Generation is correct, as it is defined by the pursuit of AI, parallel processing, and advanced software.
• D: Sixth Generation is not a widely recognized or established generation in the standard classification of computer history.

Each generation of computing is marked by significant technological advancements and shifts in focus.

The correct answer is Indentation.

• Indentation refers to the blank space inserted from the margin to the beginning of a line or paragraph. It is commonly used to visually separate paragraphs or create hierarchical structures in text.
• Line Spacing (A) is the vertical distance between lines of text.
• Margin (B) is the space between the edge of the page and the main text block.
• Justification (D) refers to how text is aligned along the left and right margins, such as left-justified, right-justified, centered, or full-justified.

Therefore, the spacing specifically at the start of a paragraph is known as indentation.

The correct answer is Gutter Margin.

• A Gutter Margin is an additional space added to the side margin, top margin, or inside margin of a document that you plan to bind. This extra space ensures that text is not obscured when the document is bound, allowing for comfortable reading.
• Line Spacing (A) is the vertical distance between lines of text.
• Indentation (B) is the space from the margin to the start of a paragraph.
• Justification (D) refers to the alignment of text along the margins.

The gutter margin is crucial for documents like books or reports to prevent text from disappearing into the binding.

The correct answer is John Eckert & John Mauchly.

• J. Presper Eckert and John Mauchly were the principal designers and builders of the Electronic Numerical Integrator and Computer (ENIAC) at the University of Pennsylvania. ENIAC was one of the first electronic general-purpose digital computers.
• Alan Turing & John von Neumann (A) were pivotal figures in theoretical computer science and architecture, but not ENIAC's founders.
• Charles Babbage & Ada Lovelace (B) are recognized as pioneers of mechanical computing in the 19th century.
• Steve Jobs & Bill Gates (D) founded Apple and Microsoft, respectively, much later in the personal computing era.

Eckert and Mauchly's work on ENIAC marked a significant milestone in computing history.

The correct answer is 1.5 line spacing.

• In Microsoft Word, the shortcut key Ctrl + 5 is used to apply 1.5 line spacing to the selected text or paragraph. This adjusts the vertical distance between lines to one and a half times the single line spacing.
• Single line spacing (A) is typically achieved with Ctrl + 1.
• Double line spacing (C) is typically achieved with Ctrl + 2.
• 5 line spacing (D) is not a standard shortcut and would be an unusually large spacing value not commonly used.

Understanding these shortcuts can significantly improve efficiency when formatting documents in Word.

The correct answer is O (which represents 0).

• To solve this, we need to know the values of sine and cosine for 90 degrees.
• The value of sin 90° is 1.
• The value of cos 90° is 0.
• Therefore, sin 90° × cos 90° = 1 × 0 = 0.
• Options (A) -1 and (D) (–1) are incorrect as the product is zero.
• Option (C) Undefined is incorrect because both sin 90° and cos 90° are well-defined values.

The product of any number and zero is always zero, making 0 the correct answer.

The correct answer is (0, –1).

• In a square, the diagonals bisect each other. This means the midpoint of diagonal AC must be the same as the midpoint of diagonal BD.
• First, find the midpoint of AC: M = ((2 + (-1))/2, (3 + (-2))/2) = (1/2, 1/2).
• Let the coordinates of D be (x, y). The midpoint of BD is ((1 + x)/2, (2 + y)/2).
• Equating the x-coordinates: (1 + x)/2 = 1/2 => 1 + x = 1 => x = 0.
• Equating the y-coordinates: (2 + y)/2 = 1/2 => 2 + y = 1 => y = -1.
• Thus, the coordinates of D are (0, -1).

This method ensures that the geometric properties of a square are maintained.

The correct answer is 260.

• This is a percentage problem. We are given that 78 students represent 30% of the class. We need to find the total number of students, which represents 100%.
• We can set up a proportion: 30% / 78 = 100% / Total Students.
• Alternatively, find the value of 1%: 1% = 78 / 30 = 2.6 students.
• To find the total number of students (100%), multiply 1% by 100: Total Students = 2.6 × 100 = 260.
• Options (A) 220, (B) 230, and (C) 250 are incorrect calculations.

Therefore, the total number of students in the class is 260.

The correct answer is 0.3333.

• To find the sum of these decimal numbers, align them by their decimal points and add them column by column, starting from the rightmost digit.
• 0.3
• 0.03
• 0.003
• 0.0003
• When added vertically, the sum is 0.3333.
• The other options represent incorrect sums due to misaligned decimal points or calculation errors. For example, 3.30003, 3.30303, and 3.00333 are significantly larger and incorrectly combine the digits.

This is a fundamental arithmetic operation involving decimal numbers.

The correct answer is 5.

• The additive inverse of a number is the number that, when added to the original number, results in a sum of zero. It is essentially the number with the opposite sign.
• For the number –5, if we add 5 to it (–5 + 5), the result is 0.
• Therefore, 5 is the additive inverse of –5.
• Option (B) O (zero) is the additive identity, not the inverse.
• Option (C) (1/5.) is the multiplicative inverse of 5, not the additive inverse of –5.
• Option (D) -55 is an incorrect value.

Understanding additive inverses is a basic concept in number theory.

The correct answer is K.

• The problem states a K×K classroom arrangement. In this notation, the first 'K' typically represents the number of rows, and the second 'K' represents the number of columns.
• The condition
  

The correct answer is Exclamation mark (!). The word 'Alas' is an interjection used to express sorrow, regret, or pity. Interjections that convey strong emotion are typically followed by an exclamation mark to emphasize the intensity of the feeling. This punctuation signals a strong emotional utterance.

• Comma (,) is incorrect because while a comma can follow a mild interjection, 'Alas' usually conveys stronger emotion.
• Period (.) is incorrect as it marks the end of a declarative sentence, not an expression of strong emotion.
• Question mark (?) is incorrect as it is used for interrogative sentences, asking a question.

The correct answer is Charles Babbage. Charles Babbage, a British mathematician and inventor, is widely recognized as the

The correct answer is Agriculture. Pakistan's economy has historically been, and largely remains, agrarian. A significant portion of its population, especially in rural areas, is directly or indirectly dependent on agriculture for livelihood, making it the largest employer and a major contributor to the GDP.

• Industry is incorrect; while growing, it employs fewer people than agriculture.
• Services is incorrect; though a significant sector, it does not engage the majority of the population compared to agriculture.
• IT is incorrect; the IT sector is emerging but employs a very small percentage of the total population.
