• John F. Kennedy, Lyndon B. Johnson, and Jimmy Carter were all U.S. Presidents, but none were associated with the Watergate Scandal. Kennedy was assassinated in 1963, Johnson served before Nixon, and Carter served after Nixon.

The correct answer is ASCII (American Standard Code for Information Interchange). ASCII is the standard character encoding system used to represent letters, numbers, symbols, and control characters in computers. When a key is pressed on a keyboard, the corresponding ASCII code is generated and processed by the computer.

Why the Other Options Are Incorrect

• ANSI: ANSI is a standards organization, not a character encoding standard used for keyboard input.
• EBCDIC: EBCDIC is a character encoding system used mainly on IBM mainframe computers.
• ISO: ISO is an international standards organization and does not itself define the keyboard character codes used in this context.

Therefore, ASCII is the correct answer.

The book Al-Futuhat al-Makkiyah, meaning 'The Meccan Illuminations', is a monumental work of Islamic mysticism and philosophy. It was authored by Ibn Arabi, a highly influential Andalusian Muslim scholar, mystic, poet, and philosopher, considered one of the most significant figures in Sufism.

The correct answer is Counts non-empty cells.

• Explanation: The COUNTA() function in Excel is designed to count the number of cells within a specified range that are not empty. This means it counts cells containing any type of data, whether it's numbers, text, logical values (TRUE/FALSE), or error values.
• Why other options are false:
• A (Counts cells having alphabets): COUNTA counts any non-empty cell, not specifically those with alphabets. To count cells with only alphabets, you would typically use a combination of functions like SUMPRODUCT and ISTEXT.
• B (Counts empty cells): The COUNTBLANK() function is used to count empty cells.
• C (Counts cells having numbers): The COUNT() function is specifically used to count cells that contain only numbers.

The UK is a classic example of a country that does not have a single, codified written constitution. Its constitution is uncodified, meaning it is derived from various sources including statutes, common law, conventions, and treaties, rather than being contained in one supreme document.

• India has a comprehensive written constitution, adopted in 1950, which is the longest in the world.
• The US has a foundational written constitution, ratified in 1788, serving as the supreme law of the land.
• New Zealand also has an uncodified constitution, similar to the UK, but the UK is the most commonly cited example for this question.

The correct answer is A range of cells from A20 to A31.

• Explanation: In Microsoft Excel, the colon (:) operator is used to define a range of cells. When you see 'A20:A31', it refers to all the cells starting from cell A20 and extending down to cell A31, encompassing every cell in column A between those two points, inclusively.
• Why other options are false:
• A (A single cell): A single cell would be referenced as 'A20' or 'A31'.
• C (A formula to calculate average): A formula always begins with an equals sign (=), for example, '=AVERAGE(A20:A31)'.
• D (A specific column labeled A20 and A31): This notation refers to a contiguous block of cells within a single column, not two separate columns or labels.

The term "sociology" was coined by Auguste Comte in 1838. This French philosopher is widely regarded as the "Father of Sociology" for his pioneering efforts in establishing the scientific study of society.

• Karl Marx was a German philosopher and economist known for his theories on class struggle and capitalism, but he did not coin the term "sociology."
• Emile Durkheim was a French sociologist who significantly contributed to the discipline's methodology and theories on social facts, but he did not originate the term.

The correct answer is The smallest resolvable part of a picture.

• Explanation: A pixel, short for 'picture element', is the smallest individual unit of a digital image or display that can be controlled or represented. Each pixel contains color information, and when many pixels are combined, they form a complete image. The resolution of an image or screen is determined by the number of pixels it contains.
• Why other options are false:
• B (A picture stored in secondary memory): A pixel is a component of a picture, not the entire picture itself, nor does it describe where the picture is stored.
• C (A computer program that draws picture): A pixel is a data unit, a building block of an image, not a program or software.
• D (A virus): A pixel is a fundamental concept in digital imaging and has no relation to computer viruses.

The Durand Line, which demarcates the border between Afghanistan and Pakistan, was formed after the Second Anglo-Afghan War (1878-1880). It was established in 1893 by Sir Mortimer Durand and Abdur Rahman Khan, the Amir of Afghanistan, as a result of British imperial policy in the region.

• The First Anglo-Afghan War (1839-1842) and Third Anglo-Afghan War (1919) occurred at different times and were not directly responsible for the line's formation.
• WWI (1914-1918) was a global conflict and not directly related to the establishment of this specific border.
