AndrewNAccording to United States Air Force officials, a cannon that shoots dead chickens at airplanes has proved helpful in demonstrating what kind of damage can result when jets fly into a flock of large birds.(E) that shoots dead chickens at airplanes has proved helpful in demonstrating
Few more questions, as I am not very grammar savy and don't have lot of knowledge about grammar, especially verbs. I would like to ask few questions
has proved is a present perfect tense ?
Yes,
has proved is written in the present perfect tense. The perfect tense adopts the form [to have] + verb. It is the conjugation of [to have] that dictates whether the tense is, say, present perfect—i.e.
has proved—or past perfect—
had proved.

also, if you had to elminate
D What would be your reasoning
Quote:
(D) that shoots dead chickens at airplanes proves itself helpful to demonstrate
D doesnt sound ok to my ears, but I cant say for sure whats wrong in
DThe idiom at the end,
to demonstrate, is simply incorrect in this context. As a lesser consideration, why do we need
itself? What does that word add in the way of clarity that
has proved helpful in choices (A) or (D) does not already convey? Whenever you see extra words, you should ask yourself this very question. If the excess does not achieve something in the way of the vital expression of meaning that the other choices lack, then get rid of such an answer choice. When I consider these two problems with (D), it is enough for me to see it off comfortably.

Also, fun fact, when you didn't have your own picture as profile Pic, your formal and polite tone in forums gave me an impression that you were an old gentlemen in his 40's.
Ha ha. I will take that as a compliment. Yes, I do tend to write in a formal manner. That is just my way. One of my professors in college, an Oxford-educated taskmaster, forbade the use of contractions in our essay papers. That is right: a single
it's or
don't would result in a returned paper for a rewrite... with one letter grade knocked right off the top, before he had even read through the paper (and he was not an easy grader at all). I was already writing in a pretty conservative way at the time, but perhaps that experience pushed me over the edge.
Thank you for seeking my input. I enjoy challenging myself and helping others in the process.
