Question

Fill in the blank with the most appropriate option
A) My sister has graduated from the university.
B) _______________________________.
a) So is my sister
b) Her sister has either
c) So has my sister
d) Neither did mine
e) So do they

Answer 1

Hint: Notice the verb used- “has”. The answer should contain the verb “has”. The answer should be in consonance with the question asked. If the question is in the positive, the answer shall be positive and if the question is negative, the answer will be negative.

Complete answer:
 The correct answer is option c because the answer we are looking for should convey the fact that my sister has also graduated from the university.
Option a is wrong because the verb used is “is”. “Is” means to be something while “has” means to do something. The correct way of using “So is my sister” is-
My sister is living in America. So is my sister.
This implies that my sister is also living in America.
Option b is a meaningless and incomplete set of words. Either is used when there is a choice- You can drink either tea or coffee. In the given question, there is no need for such a choice.
Option d is wrong because the answer is in the negative. The answer would have been correct if the question was something like “My sister has not graduated from the university”, to which the answer would have been “Neither did mine”.
Option e is wrong because it is not an answer specific to the given question. The usage of such an answer is: “They like to attend concerts of famous singers.” “So do they.”

Note:
 If students are confused between options a and c, always remember to use the same verb in the answer. Understand what the sentence is trying to say and select your answer accordingly. The answer should be in tandem with the statement above it.
