Question

Complete the sentence with the most suitable option:
Doctors often use X-rays __________ they can pass through skin and flesh.

• A. So that
• B. As long as
• C. Provided
• D. Nevertheless

Answer 1

Answer: (A)

So that

The conjunction is a word used to connect other words, phrases or clauses.

Subordinating conjunction connects or joins an independent clause with a subordinate clause. 'So that' is used to talk about a purpose. The given sentence talks about the purpose of using X-rays. 'As long as' is used to refer the intended duration of a plan or an idea. It mostly refers to the future situation. 'Nevertheless' is used to indicate that the second point made contrasts with the first point. 'Provided' is used to mean that one thing happening is dependent on another thing happening.

Thus, option A is the correct answer.
