Sure:
17) D
19) A
20) C
In the attachments, the first three of them are the ones I don't understand...
15) The answer is B but I don't understand why it cannot be A
18) I don't understand any part of it.
10) I know it can't be C or D but other than that, I have no idea
BPunjabi:
So with first attachment you rule out c) and d) because they are not commercial and are not businesses. A) is ruled out because an atm does not look at sale data, it is simply used for getting money out. Therefore b)
Let me think about second one
Third one is b) because all the other answers have a surname as a primary key, when primary keys can only be like an id number. For example s7170 or just 011837 cant be words like ford, opal.. cant be any type of word
Is the last one b) or a)?

Yea now that you point it out, the third one was easy - I didn't think about why a surname can't be a primary key - Thanks!
The last one is B because it's not an intranet
BPunjabi:
Second one is c) am i right?
