Option D In context, the pronoun it has no clear antecedent. The second part of the sentence begins with because, and therefore is giving a reason for something mentioned in the first part of the sentence. Clearly, it is explaining why we adopt superstitions, according to the scientists mentioned in the previous sentence.

 Option B. In the last line the author says that Indian business scene is a unique mix of features of various international markets. Option B is closest to this view and hence the answer.

Option (D)

The passage mentions some compounds such as alkaloids, terpenes, and flavonoids that are broken down during carbon cycle. So we can answer I. Also, the passage says that bacteria and fungi catalyze the oxidation of inert products which triggers reactions to produce carbon dioxide. Hence we can answer III.

Option (D). The author explicitly states in the passage that the essence of Einstein’s science lay in his artistry- his phenomenal sense of beauty. (refer the first line of the passage)

Option C.

The author says that green plants produce many compounds that cannot be used by the plants as sources of energy. He goes on to say that degradation of these compounds leads to release of carbon dioxide and so return much carbon to a form that actively enters into life cycles once again. Hence option C.

Option B.

The passage says that Einstein found fame incomprehensible, but that Chaplin was worldly-wise, and Chaplin’s response to Einstein demonstrates that he understands the nature of celebrity. Moreover the passage states that Einstein was bewildered seeing the crowds surge him but Chaplin was not. This makes option (b) correct.

Option C. Einstein’s question is asking why people are treating him like a celebrity. This behavior of the “public” can be termed a social phenomenon. Option C is hence correct. We can easily eliminate options A and B as they are not related to the passage. People’s behavior is not politically motivated and hence option D is eliminated.

 Option (B) 

In the passage, the author says that bacteria and fungi act as catalysts in oxidation of inert products ultimately leading to release of carbon dioxide. Inert compounds are those which do not react with other compounds. As per option B, most compounds containing carbon cannot be used as energy sources by organisms except bacteria and fungi. This would strengthen the author’s opinion that bacteria and fungi play a crucial role.

The phrase who is as good as him is a subordinate clause. A subordinate clause requires the pronoun “he”, not “him”. The implied meaning of the phrase is “as good as he is”. “As good as him is” is grammatically incorrect.

Therefore (B) is correct.

Good is an adjective. It modifies nouns. Well is an adverb. It modifies verbs. Since him is a pronoun, it should be modified by an adjective, not an adverb. Therefore (A) is incorrect. Single quotation marks are appropriate for both a quote within a quote and a word that is not being used for its meaning. Since someone is being quoted and quoting the word tattooed on Justin, single quotes are appropriate. The emphasis is on the word Blessed,which is part of the quote. Therefore (C) is incorrect. The word lest means so that something will not happen. For example, We should get out of the rain lest we catch cold. This meaning does not make sense in the sentence. Therefore (D) is incorrect.

Option (C)

Maria begins her letter with a statement that closing the museum on Saturdays will cause her and others hardship. Maria then goes on to describe the many positive effects the museum has had on the town. Maria next states that additional taxes are merited for keeping the museum open on Saturdays. Maria urges the readers to help the museum get this funding. What Maria wants is for the reader to support additional tax revenue for keeping the museum open on Saturdays. Maria attempts to convince the reader to support this cause by showing the reader how great the museum is and how much of a hardship it would cause to close the museum on Saturdays. Maria wants to persuade the readers to support her cause. Therefore (C) is correct.
