Multiple choice question (The next day she felt ... well to go to work.)

[Nessie]

1/ Brenda: Do you think it will rain?
Helen: Oh! ...
a. I don't hope so
b. I don't hope
c. It's hopeless
d. I hope not
=> which is the better choice here, a or d?

2/ The next day she felt ... well to go to work
a. suffice
b. sufficiency
c. sufficiently
d. sufficient
=> The answer is surely c, but I just wonder if the use of "sufficiently" here is correct (language style), and if it is, then how different is it compared to enough?

Many thanks
Nessie

1.
Choice d sounds the most natural to me.

2.
Sufficiently is the only option that works grammatically. If you used the word 'enough', you would have to change the word order to 'felt well enough'. I think 'felt well enough' sounds more natural than 'felt sufficiently well'.

Thanks, Amy I also think using "enough" here is more natural than "sufficiently" here. And could you please be more specific about the difference between "enough" and "sufficient".
Thanks a lot
Nessie

P.S: By the way, dear Amy, could you please tell me if we should use a exclamation mark or a question mark at the end of such questions as "could you please..." (I mean: they are questions, but not really used for asking. They are used for inquiring something, so is it all right for us to use an exclamation mark rather than a question mark?)
Many thanks :)
