Answer:
Your conclusion is your chance to have the last word on the subject.
Okay, for the first one the anwser is D, for the second question the answer is B.
That means it's offered for sale at a very very very very good price.
The price may be so good because the owner doesn't know what it's actually worth,
or because they're having a super-duper temporary sale, or because it's something
you personally need very badly so it's worth a lot more to you personally.
In any case, it's called a 'steal', because when something is stolen, the stealer
gets what he wants for a very very very low price, and this is just like that.
A should be the right answer
