Thank you Roberta and Set for taking time to answer. Set don't pick on me I can't help it my hempster comes with me wherever I go.
Let me explain, I am Turkish, even though I lived in Long Island,New York almost 20 years (I was 24 when I immigrated.)
I graduated high school in Turkey and having 2 hours a week English classes for 3 years didn't help much as you can tell.(NO college education)
Now I am back in Turkey and came across a language forum while surfing the net, this forum is for Turkish students who are preparing to take University Entrance exams, having nothing much to do on the net I became a member and thought maybe I could help these kids a little.
I was under the impression that I spoke pretty good English and possibly had something to offer.
Guess what, I was dead wrong.
So now from time to time I face questions that are so ambiguous I find myself feeling like a one legged man in a ass-kicking contest.(little humor there, not bad for a Turk with no college education huh.
)
I agree with you that these questions are badly written, probably by a half ass English speaking Turk like me, who knows.
When I saw this this site and forum on one of my google searches light bulb went on and I thought I can ask you native speakers about these questions.
I hope you don't mind I'll be picking your brains from time to time, like the song says:
I am just a soul whose intentions are good.
Stay healthy and happy.
(I used to pump gas , ended up owning couple of gas stations on Long Island thus the nick.)
P.S. Roberta on second question I was defending the choice ''efficiency''
since my understanding of the sentence was they were talking about the amount of fossil fuels world must use not the total fossil fuels world has.
