There when the crime happened, i only heard about it afterwards. 1. was 2. was not 3. were not 4. will not

The question seems a bit incomplete but I believe the correct answer should be 2. was not.

That would correctly complete the sentence like so:

I was not there when the crime happened, I only heard about it afterwards.

2. Was not would be correct sine they only heard about it afterwards

My favorite color is light blue. I like that color because first it's a sky color and second of all a lot of people like blue
