In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'. There is a general agreement that some behaviors that are common in birds (1)/ as well as in crocodiles, was also common among (2)/ extinct dinosaur groups. (3)/ No error (4)?

Option 2 : 2

The correct answer is '2' i.e. error lies in part 2 of the sentence.

In part 2 of the sentence, the usage of 'was' is incorrect Instead, use 'were'

• According to grammar, whenever we have used the singular verb we need to use a singular verb and with a plural noun, we have to use a plural verb.
• In the given sentence, the noun 'behaviors' is a plural noun hence there should be a plural verb for it. 'Some' is a determiner i.e. used for 'behaviors'

So the correct sentence is- There is a general agreement that some behaviors that are common in birds as well as in crocodiles, were also common among extinct dinosaur groups.
