Q. Fill the correct form of verb in the given sentence. Either of these two pens ________ good.
a) are
b) have
c) is
d) has
Correct Answer: c) is
Question from UPPSC Prelims CSAT 2025
Explanation:
Subject-verb agreement: ‘Either of + plural noun’ takes a singular verb because ‘either’ refers to one of the two. Since ‘good’ is an adjective, the correct linking verb is ‘is.’
– ‘are’ (plural) is incorrect.
– ‘have’ and ‘has’ require an object (e.g., ‘has good quality’) and do not link to an adjective directly.
Therefore: ‘Either of these two pens is good.’
