Hi all,
Try to split and resplit the asnwer choices by looking at the begining and at the end of the sentence.
Read It vertically. Scan and Kill it.
(RiSK) (c)So what do you see here. Look the following splits:
1) A, B - begin with
a source of income, C- with
and, D, E- begin with
which 2) Plural A, C, D/singular - B, E
Decide what is wrong let say in 2). subject "Declining revenues" - they are or it is???! Must be
they are. So cross out B, E.
now go to 1) we have still 3 different subsplits A, C and D.
which must refer to the noun just before it. Is
travel is a source of income? not for us. Kill D and move on.
Make sure you have crossed out B,E and D. Now you have 50% probability to get this SC right.
Now, even if you are stuck between choices A and C, read C carefully. Do you see smth wrong ?
first,
it is ambigous here, to what does it refer? seems to business travel, is it really so ? nope.
second,
to survive with - is awkward ask yourself with what??! why infinitive?
third,
and is used in either parallel structures or enumeration, do you see that neither of cases is applicable to C? Cross it.
So answer is A.
