I have four questions to ask:
Most economists today agree that if ___________ than 5 percent of the labor force is unemployed, the economy for all practical purposes, is in a state of full employment.
a. less b. no more
The key is 'b'. I think 'b' can mean 'up to five percent'. 'a' means '1-4'. My question is: can I choose 'a'? "no more than 5 per cent" = I agree with your suggestion. "Less than 5 per cent" is between zero and 5 per cent. You could certainly use it, and the sentence would be grammatical. NB no comma after "purposes".
Bob said proudly that he had achieved all his goals, not in spite of his handicap, but _______.
a. owing to b. due to c. on account of d. because of
I think the sentence means: His handicap didn't prevent him from achieving his goals. I agree
The key is 'd'. This is too difficult for me because I can't see the difference here. There is a basic problem in that there has to be something after the options offered - "handicap, but on account of it".
_______ I had the money, I wouldn't buy such an expensive thing.
a. Unless b. Even if
The key is 'b'. Can I choose 'a' to mean 'If I want to say ' When I have money I would buy such an expensive thing'? I think "Unless" is synonymous here with "Except when". It indicates less guarantee that you will have the money.
He is a controversial person, but his science fiction books are ______.
a. admired by both his friends and opponents
b. admired both by his friends and opponents
The key is 'a'. No problem. If I choose 'b' it should be ' admired both by his friends and by his opponents'. Is that right? I agree with you.
Looking forward to hearing from you.
Thank you in advance.
