Does this question have different options?

Hi, Cnjackie!

When is the assignment due?

Come on! I'm not a student. It's also not a assignment.

How are we supposed to know that unless you tell us?

You can put that information in a signature line by clicking on Settings and then Edit Signature.

This seems very straightforward to me. The correct answer is C. The other answers are not correct. (See post #6)

Remember that for this type of gap-fill question, when the sentence including the gap is accompanied by other sentences, those other sentence are there to make the 'gapped' sentence make sense. In other words, you must select your answer in light of the whole context.

So, which answer is correct?
As most of you are native speakers, but it seems some of you also have different ideas.

The correct answer is C.

— David promised to come round to have supper with us today.  
— But he ____. I’ve been alone for half an hour.  
A. won’t 

No. We don't know whether he will or won't. We can't predict the future.

B. hadn’t 

No. You're in the present (you're alone now, waiting), so your verb needs to be a present tense.

C. hasn’t   

Yes. He was supposed to arrive, but so far, he hasn't.

D. doesn’t 

No. I think we all agree that that one makes no sense.

As you can see, Jackie, native English speakers don't always agree.

But I'm right.

Other business: The first sentence says "us," but the last sentence says "I." Where did everyone else go?

For me, the "us" refers to the two speakers. I take the long dash before "David" and the one before "But" to mean that they are spoken by two different people. I assumed (perhaps incorrectly) that speaker 1 has only just arrived and speaker 2 had been alone for the half an hour before speaker 1's arrival.

I think the replying part should depend on the time. Suppose they have finished supper, and they're ready to go.

That won't work. How could they have eaten together if one of them has only just arrived?

They think David will not come.

Then it would be phrased differently:

— David promised to come round to have supper with us today.
— But he didn't. I’ve been alone for half an hour.  

Won't would be grammatical, but it isn't natural.

So only C works.

[emsr2d2]

If it had been a "Put a word in the gap (free choice)" exercise, I would have put "didn't" there too. Unfortunately, that wasn't one of the options. The only one of the four given that works is "hasn't".

"He hasn't [come]" does at least leave open the possibility that he will still turn up.

The correct answer is C.

Welcome back, jutfrank. We've missed you.

If you've had the virus, I hope you're better.

Thanks very much. It's nice to be back.

I haven't had the virus but I appreciate the concern. I'll be dropping in sporadically over the coming weeks. In the meantime, I hope everybody here stays happy and healthy.
