Subject Verb Agreement

Front

Carlos is the only student who __________ lived up to the potential in the yearbook.

Back

a. has

Answer explanation

"has"

The 'who' refers, in this case, to 'the only one,' which is singular.

Front

The International Club, Choral Society, and Rowing Club __________ to submit a new constitution.

Back

b. needs

Answer explanation

You're right! (But check the Explanation to see if your reasons for making this choice are the same as ours.)

The subject here is 'The International Club,' which is singular. The modifying phrase that comes after 'as well as' modifies the subject but does not compound it as the word 'and' would do.

Front

Most of the milk _____ gone bad. Six gallons of milk _______ still in the refrigerator.

Back

a.has ---- are

Answer explanation

'Most' is not a countable noun here (you can't count 'the milk' in the first sentence), so the verb must be singular. You can count the gallons of milk, though, so the subject in the second sentence is plural.

Front

Four years _______ a long time away from friends and family.

Back

a. is

Answer explanation

The quantity of 'four years' here is meant to be taken as a whole, as one quantity, so the verb should be singular.

Front

Economics of this country ________ to be in disarray.

Back

A. seem

Answer explanation

‘Economics,’ in this case, means any number of aspects of or facts about the country’s financial health, so we need a plural verb. When the word ‘economics’ refers to the course or the discipline, it is singular.

Front

A large number of voters still ___________ along straight-party lines.

Back

a. vote

Answer explanation

‘Number’ is a collective noun, but the elements within the collective noun, the voters, are acting separately in this case (we hope!), so the verb should be plural: ‘vote.’

Front

Carlos is the only student who __________ lived up to the potential in the yearbook.

Back

a. has

Answer explanation

The ‘who’ refers, in this case, to ‘the only one,’ which is singular.

Front

A pack of lions _______ approaching the camp.

Back

a. was

Answer explanation

The subject " a pack of lions" is considered as singular noun so the verb shoul be singular as well.

Front

Neither me nor my parents ________ aware of the incident.

Back

were

Answer explanation

Two subjects are accompanied by " neither.........or" so only the subject after " or " will have any effect on the verb.

Front

Back

a. was

Answer explanation

"jury" is a collective noun which is always considered as singular subject.
