The correct option to complete the sentence "We ought to stay away .... the robbers come back" is
D. in case.
Step-by-Step Explanation:
- Understanding the Sentence Context:
-
The sentence suggests a precautionary action. The phrase "We ought to stay away" indicates that there is a reason to avoid a certain situation, which in this case is the potential return of robbers.
-
Analyzing the Options:
-
A. provided: This word typically introduces a condition, meaning "if" or "on the condition that." For example, "We will go to the park provided it doesn't rain." In this context, it does not fit because we are not stating a condition but rather a precaution.
-
B. should in case: This option is grammatically incorrect. The phrase "should in case" does not make sense in standard English. The correct phrase would be "just in case," but that is not one of the options. Therefore, this option is not valid.
-
C. although: This word is used to introduce a contrast or concession. For example, "Although it was raining, we went for a walk." In this context, it does not fit because we are not contrasting two ideas; we are expressing a precautionary measure.
-
D. in case: This phrase is used to indicate a precaution taken to prepare for a possible future event. It means "as a precaution against" or "if something happens." In this sentence, it correctly conveys the idea that we should stay away as a precaution in the event that the robbers return.
-
Why Option D is Correct:
-
The phrase "in case" effectively communicates the intention behind the action of staying away. It implies that the action is taken to avoid potential danger, which aligns perfectly with the context of the sentence.
-
Common Pitfalls:
- Students often confuse "in case" with "if" or "provided," which can lead to incorrect choices. It's important to recognize that "in case" is specifically about taking precautions for possible future events, while "if" and "provided" are more conditional.
Revision Summary:
- The correct answer is D. in case because it indicates a precautionary measure.
- "Provided" introduces a condition, which does not fit the context.
- "Should in case" is grammatically incorrect.
- "Although" introduces contrast, which is not relevant here.
