Join the words or sentences with the conjunctions correctly from the o...
To join the given sentences with the correct conjunction, we need to choose the option that provides a logical connection between the two sentences. Let's analyze each option:
A.
While: This conjunction is used to indicate a contrast or simultaneous action. However, it doesn't make sense to use "while" in this context as there is no contrasting action or simultaneous occurrence mentioned in the sentences.
B.
If: This conjunction is used to express a conditional relationship. It implies that the second sentence is a possible consequence of the first sentence. In this case, it is appropriate to use "if" as the second sentence can be seen as a potential result of catching fever.
C.
For: This conjunction is used to indicate a reason or purpose. However, using "for" in this context doesn't provide a clear connection between the two sentences.
D.
Or: This conjunction is used to present alternatives or choices. It doesn't make sense to use "or" in this context as there is no alternative or choice mentioned in the sentences.
Therefore, the correct conjunction to join the given sentences is
"if", making the combined sentence: "You may catch fever if you still wear this thin dress." This implies that wearing the thin dress may lead to catching fever.
Answer: B
