Question

Choose the correct answer to fill in the blank from the options given.
A swarm of bees ________ building a hive outside the house. [Basic]

• A. is
• B. are
• C. am
• D. were

Answer 1

The correct option is A is

Here, swarm is a collective noun. Thus, A swarm of bees means one swarm, containing many bees. Options B and D indicate a plural sense hence, they can be eliminated. Option C is used when the entity is referring to itself and hence this too can be omitted. Hence the correct answer is A. 'is'.

Thus the correct sentence is:

A swarm of bees is building a hive outside the house.
