IDAT - International Diagnostic and Admission Grammar and Sentence Structure Questions and Answers

Question 1

Which of the following sentences is grammatically correct?

Accepted Answer

The flock of birds flies south for the winter.

Answer

The correct answer is 'The flock of birds flies south for the winter.' This is because the subject of the sentence is 'flock,' which is a singular collective noun. Therefore, it requires a singular verb, 'flies.' The other options contain subject-verb agreement errors: 'team' is singular but is paired with the plural verb 'are'; 'Each' is singular but is paired with the plural verb 'are'; and 'news' is an uncountable noun that takes a singular verb, so 'were' is incorrect.

Question 2

Read the following sentence: 'The manager, whom is responsible for the entire department, will be holding a meeting tomorrow.' Which part of the sentence contains a grammatical error?

Accepted Answer

whom is responsible

Answer

The error is 'whom is responsible'. 'Whom' is an object pronoun, but in this context, a subject pronoun is needed because it is the subject of the verb 'is'. The correct pronoun to use is 'who'. The corrected phrase would be 'who is responsible'.

Question 3

The student diligently worked on the assignment ______ he was feeling unwell.

Accepted Answer

although

Answer

The word 'although' correctly shows the contrast between the two ideas in the sentence: the student's diligence and his feeling unwell. 'Because' and 'so' would imply a cause-and-effect relationship that doesn't fit the context, and 'therefore' indicates a result, which is also illogical here.

Question 4

Which sentence correctly uses punctuation to join two independent clauses?

Accepted Answer

The concert was fantastic; the band played all of their hits.

Answer

A semicolon (;) is used correctly here to connect two closely related independent clauses. Choice A is incorrect because a semicolon or a period should precede 'however'. Choice C is a comma splice, where two independent clauses are incorrectly joined by only a comma. Choice D is a run-on sentence that lacks any punctuation between the two clauses.

Question 5

After reviewing the security footage, the manager identified the person ______ left their wallet at the counter.

Accepted Answer

who

Answer

The correct pronoun is 'who'. 'Who' is used as the subject of the verb 'left'. 'Which' is used for things, not people. 'Whose' is possessive. 'Whom' is an object pronoun and would not be correct here as the subject of the verb.
