The word "Prodigal" means spending money or resources freely and recklessly; wastefully extravagant. Therefore, its synonym is Extravagant.

• Humble means having or showing a modest or low estimate of one's own importance, which is the opposite of prodigal's connotation of excessive spending.
• Arrogant means having an exaggerated sense of one's own importance or abilities, which is unrelated to spending habits.
• Trivial means of little value or importance, which does not relate to the concept of wasteful spending.

The word "for" in the sentence "After lunch let's go for coffee" functions as a preposition. A preposition is a word that shows the relationship between a noun or pronoun and other words in a sentence, often indicating direction, time, place, or purpose. Here, "for" indicates the purpose or destination of going, connecting "go" with "coffee".

• Adverb is incorrect because adverbs modify verbs, adjectives, or other adverbs, and "for" is not doing that here.
• Noun is incorrect as "for" is not a person, place, thing, or idea.
• Adjective is incorrect because adjectives describe nouns, and "for" does not describe any noun in the sentence.

In literature, an epilogue is a section or speech at the end of a book, play, or film that serves as a conclusion to the main story. It often provides insight into the future of the characters, ties up loose ends, or offers a final reflection on the themes presented. It acts as a concluding remark or a short poem.

• Option A (Prologue) is an introductory section or speech at the beginning of a literary work, setting the stage for the story.
• Option B (Dialogue) refers to a conversation between two or more characters within the story.
• Option D (Monologue) is a long speech delivered by a single character, often revealing their thoughts or feelings, but it is not necessarily a conclusion to the entire story.

Dowry is a payment of money or property by the bride's family to the groom or his family at the time of marriage. Historically, dowry has been a deeply entrenched custom in many cultures, particularly prevalent in the context of arranged marriages in regions like South Asia.

However, due to its exploitative nature and association with violence against women, dowry is now legally prohibited in many countries, especially where arranged marriages are common. Laws like the Dowry Prohibition Act in India specifically target and outlaw dowry in all forms of marriage, including arranged ones.

• Options A ('Natural marriage') is not a recognized legal or sociological term.
• Option C ('Court marriage') refers to a civil marriage process, not a type of marriage where dowry would be permitted.
• Option D ('Forced marriage') is a human rights violation, and while dowry might be a factor, the question asks where it's 'no longer permitted', referring to a legal prohibition against a traditional practice.

The Least Common Multiple (LCM) of two or more integers is the smallest positive integer that is a multiple of all the numbers. To find the LCM of 27 and 63, we can use prime factorization.

• First, factorize each number: 27 = 3 x 3 x 3 = 33 and 63 = 3 x 3 x 7 = 32 x 7.
• To find the LCM, take the highest power of all prime factors present in either number: 33 x 7 = 27 x 7 = 189.

Therefore, 189 is the smallest number that is divisible by both 27 and 63.

• Options B (54), C (81), and D (126) are multiples of one number but not both, or not the least common multiple. For instance, 54 is 27 x 2 but not a multiple of 63.

A byte is a fundamental unit of digital information in computing and telecommunications. It is universally defined as consisting of 8 bits. This standard allows a single byte to represent 28, or 256, distinct values, which is crucial for encoding characters, small integers, and other data. For example, the ASCII character set uses one byte per character.

• Option A (4 bits) describes a 'nibble', which is half a byte.
• Option C (16 bits) is equivalent to two bytes, often referred to as a 'word' in some older computer architectures.
• Option D (32 bits) is four bytes, commonly known as a 'double word' or a typical word size for many modern processors.

The correct answer is "All of these". Water sagacity, meaning the wise and prudent use of water, is critically important across all sectors to ensure sustainability and efficient resource management. Each listed sector has significant water demands.

• "Industrial use" requires careful water management to minimize waste and pollution.
• "Domestic use" involves daily household activities where conservation efforts significantly reduce overall consumption.
• "Agricultural use" is the largest consumer of fresh water globally, making efficient irrigation and sustainable practices vital. Therefore, responsible water management is essential in every listed area.
