Spotting Errors

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.
