Question

A snake __________ by him before



Has been killed

have been killed

killed

is kill

​

Answer 1

Sentence given :

A snake _____ by him before.

Options given :

• has been killed
• have been killed
• killed
• is kill

Answer : has been killed

HOW?

→ Here, by the sentence it is mentioned before which means the sentence is in the past tense. So, the last option "is killed" is cancelled. And then, even it is in past it is inappropriate and wrong to use "killed". So 2 options are left , and here the word "snake" is a singular noun. So, we can't use "have been killed". Thus, "has been killed" is the correct answer.

So, done!

$\large\fbox\color{green}{Explanation}$

According to the Question, the action happened here is in past. So we cannot use "is kill". Then if we see the third option - "killed", it cannot be inserted in the blank even though it's in past tense because it's form in past doesn't suits the question. So third option is also wrong. Now we have two options left. In the question, it is mentioned 'snake' which is in singular form. So we cannot use "have been killed". Finally, the one option left is "has been killed", which perfectly fits the blank. So the Correct answer is Option: A [Has been killed].
