We  (not go) out because it  (rain).a.did not, rainedb.did not, rainedc.did not, was rainingd.do not, rained

To fill in the blanks in the sentence "We (not go) out because it (rain)," we need to choose the correct options from the choices provided.

Analyzing the Options

1. a. did not, rained - This option is incorrect. "Rained" is the simple past tense and doesn’t logically fit in the sentence structure for the ongoing action.

2. b. did not, rained - This is the same as option a and is also incorrect for the same reason.

3. c. did not, was raining - This option uses the correct past negation for the first part "did not go" and an ongoing action with "was raining." It fits the context well since it implies that it was raining at the time they did not go out.

4. d. do not, rained - This option is incorrect because it uses the present simple tense "do not go," which does not fit well with the past context implied by "because."

Final Answer

The correct completion of the sentence is: "We did not go out because it was raining." Therefore, the correct choice is c. did not, was raining.
