Subject-Verb Agreement

The subject 'cost' is a singular noun, but the verb 'have' is plural. This violates subject-verb agreement rules. The correct verb should be 'has' to match the singular subject 'cost'.

The correct idiomatic expression is 'keep one's word' (singular), not 'keep one's words'. When someone promises to do something and follows through, we say they 'keep their word'. The error is in part B.

In interrogative sentences starting with 'shall', the subject comes after the auxiliary verb. The correct order is 'Shall you read this book for me?' - which is grammatically incorrect. Modern English uses 'Will you' or 'Would you' instead for polite requests. The error is indeed in A.

With 'either...or' construction, if one subject is singular and the other is also singular (Ganesh/Ganpat are both singular), the verb should be singular. 'Have' is plural - the correct form should be 'has' to match the singular subject. Error is in part C.

The pronoun 'theirs' is incorrect in this context. We're referring to 'the very glimpse' of them, which should use the possessive adjective 'their' or rephrase as 'of them'. 'Theirs' is a possessive pronoun used independently (like 'the book is theirs'), not as an object of a preposition referring back to a noun.

When using 'except' with a subject pronoun, we use the objective case 'me' not the subjective case 'I'. The correct phrase should be 'except me' as it's the object of the preposition 'except'. Subjective 'I' is incorrect here.

(was) In case of 'either-or', 'neither-nor', the verb connects with the second subject. 'Staff' is singular collective noun.

 Option 3 is where the error is. In the context of the sentence, we would replace "expected" with "expecting".

The correct answer is B because 'boy' should be 'boys'. After 'Each of the', the noun must be plural (e.g., 'Each of the boys'). 'Each' is singular, so it takes a singular verb, but the noun in the prepositional phrase must be plural.

The correct answer is B because 'who absent' is grammatically incorrect. It should be 'who are absent' or 'who were absent' - a verb is required after the relative pronoun 'who'.

The correct answer is D because 'have' should be 'has'. The subject is 'Each' (singular), not 'radioisotopes'. 'Each of the radioisotopes' requires a singular verb: 'has' not 'have'.

 Since plural form...visas is being used we cannot use it ...... Correct phrase will be, 'have them'

 There are no errors in this sentence. It is grammatically correct.

The correct answer is B because 'are' should be 'is'. Amounts of money, time, and distance are treated as singular in English. 'Ten million dollars' is a singular concept requiring a singular verb.

The correct answer is C because 'its' should be 'their'. The antecedent is 'seismic waves' (plural), so the pronoun must be plural ('their' not 'its'). The possessive pronoun must agree in number with its antecedent.

The correct answer is B because 'enable' should be 'enables'. The subject is 'The Zoning Improvement Plan' (singular), so it requires a singular verb. The phrase 'better known as zip codes' is an interrupter and doesn't change the subject.

The correct answer is C because 'are' should be 'is'. The subject is 'Everyone' (singular indefinite pronoun), which requires a singular verb. The intervening phrase 'who has travelled...' doesn't change the number of the subject.

The sentence is grammatically correct and uses appropriate parallelism and prepositional phrasing. No part of the sentence contains an error.

The correct answer is C because 'need' should be 'needs'. The subject is 'a group' (singular), not 'singers or musicians'. When using a collective noun like 'group', the verb must agree with 'group', not with the complement.

The correct answer is D because 'their' should be 'his'. The antecedent is 'Thor Heyerdahl' (singular), so the pronoun must be singular ('his' not 'their'). While modern English sometimes uses 'their' as singular, in formal grammar and on standardized tests, singular antecedents require singular pronouns.

The subject 'Most MBAs' is plural (referring to multiple MBA graduates), so the verb must be plural 'earn' not 'earns'. Additionally, the comparison 'as managers' uses the plural form to match the plural subject, making option C grammatically correct.

The subject is 'Most lachrymose of soap operas' which refers to multiple soap operas, so the verb must be plural 'capture' not singular 'captures'. The phrase 'of viewers' is more idiomatic than 'of the viewers' in this context.

 What is the reason? 'Sedentary life-style' (and not faulty food habits) is the major reason. 

The preposition 'between' requires the objective case for pronouns. 'I' changes to 'me' and 'he' changes to 'him'. The correct word order is 'him and me' following conventional English usage.

The verb 'prevent' is typically followed by either a possessive form plus gerund ('prevented his taking part') or an object form with 'from' ('prevented him from taking part'). Option B uses the correct possessive + gerund construction.

 'makes them'
 The usage of 'along with' means that the verb will connect with the first subject, which is singular 'high protein content'.

'Population' is a mass noun in this context, referring to people as a collective whole. Mass nouns take 'much' rather than 'many' for quantification. The correct phrase should be 'much of the world's population'.

When comparing one thing to others using 'one of the...', the noun that follows must be plural. 'Population density' is what's being compared, so it should be 'one of the lowest population densities' (plural). The singular 'density' is incorrect.

In this context, 'automobile' is used as a mass noun referring to automobile manufacturing in general, so the singular verb 'was' is correct. However, the pronoun referring back to it must be plural 'them' to match the idea of multiple automobiles being produced.
