as far as i know, "would" is always used in a construct where we are dealing with "past tense". When i was working out this problem, i just eliminated the options "would" Can u plz shed some light on this..
“WOULD” AND “COULD” These words have 2 different incarnations.
Usage #1 “Would” is the past tense of “will”, and “could” is the past tense of “can”. e.g. According to his most recent advertisement, Mookie the Bookie can predict with 100% accuracy which teams will win next week’s games. vis-à-vis His October 2, 1982, advertisement declared that Mookie the Bookie could predict with 100% accuracy which teams would win the following week’s games.
Usage #2 “Would” and “could” are used to describe hypothetical situations that are not true. (since these situations are hypothetical -- i.e., they never happened -- they don't really have a timeframe.) e.g. If I had one million dollars, I could buy 800,000 hamburgers at the gas station. If I had one million dollars, I would donate 800,000 hamburgers to the county food bank.
