Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. whether.
The sentence is: 'Can we see (1)________ the earth is a globe?'
Here, the sentence is asking a yes/no type of question — it is not asking for a place (where), not making a statement (that), and not proposing a condition (if).
The correct conjunction to use when asking an indirect yes/no question is 'whether'.
Let’s examine the options:
where – used for place → incorrect.
that – used to introduce a clause stating a fact → incorrect.
if – although sometimes used for yes/no questions, “whether” is more formal and preferred when followed by a clause (like “the earth is a globe”) → “whether” is better here.
whether – correct usage for indirect questions → Correct answer.
Final sentence: Can we see whether the earth is a globe?
