Past possibility... 

What's your guess?

wolfgirl3_ · Answer

the first one

whitemonsterbunny17 · Answer

'May' means that there is that possibility, but in this case it is a possibility in the $\underline{future}$. 
We need to find one that indicates that it could have happened in the past.

the second one then

whitemonsterbunny17 · Answer

Why?

wolfgirl3_ · Answer

i answered means that she answered it which mean it was in the past

whitemonsterbunny17 · Answer

You're partially correct; it is in the past, yes. 
However, we have to find one that indicates the $\underline{possibility}$ of it happening. This one just blatantly states that it happened. 

I did it (I did something in the past).
I could have done it. (I possibly did something in the past).

i have no more ideas on what the answer could be could you tell me what u think

whitemonsterbunny17 · Answer

I can't blatantly tell you the answer, that's not how it works here. 

I think you can get it... Take a look at this example: 

$\bf{I~}\color{lime}{could~have~}\color{turquoise}{went~}\color{black}{to~the~beach.}$

'Could have' is in green, as it shows the $\bf\color{lime}{possibility}$ of something happening. 
'Went' is in turquoise, as it shows a $\bf\color{turquoise}{past~tense}$ word which indicates that this occurred (or could have occurred) in the past.

With that said, what's your next guess?

wolfgirl3_ · Answer

the third would i believe is right

whitemonsterbunny17 · Answer

Why's that?

wolfgirl3_ · Answer

that answer cause i could have is pass tense and makes it in the pas

whitemonsterbunny17 · Answer

'could have' indicates the possibility in the past tense, yes. 
'answered' is a verb in the past tense which shows that the action occurred in the past.

thanks for the help even if it took me awhile to finally get the right answer

You are welcome. 

It is time-consuming, yes. The whole point of this is to help you to really $\bf\color{lime}{learn}$ and $\bf\color{magenta}{understand}$ the material.
