E?
I don't think "shooting" is right here. We need "that" to modify the cannon. The leaves choice D and E. I picked E because proved...in...ing

Straight E

Semantic question

Could you please explain why E?

I get mighty confused between when to use "shooting" vs "that shoots"

(A)a cannon shooting dead chickens at airplanes has proved helpful to demonstrate
(b)a cannon that shoots dead chickens at airplanes has proved helpful in demonstrating

Lets just ignore the "helpful to demonstrate" vs. "helpful in demonstrating" for now.

It's the cannon that HAS proved helpful, not the chickens shooting out of the cannon (that's actually NOT helpful!).

proves helpful etc isn't a real sentence

so it's E

Original is wrong 'cos cannon shooting dead chicken the sounds like all the words in RED modify chicken.

a relative pronoun "that" makes things clear by indicating that the cannon is shooting dead chicken and also introduces a clause.

"In demonstrating" is a noun clause in the objective form.

E stands

choose E.

b. helpful as a demonestration - never heard such an expression.......
c. helpful as demonstrating - similar to b.
d. helpful to demonstrate - same as a.
e. helpful in demonestrating - sounds good.

As mentioned by someone above

Its the cannon which has prooved helpful and not the chickens. Thus A, B and C are straightaway out.
And I believe it's easy select between D&E.

Besides there're a lot of online articles which use "helpful to demonstrate", thus not idiomatically wrong.

In the given choices "ing" can't be completely avoided. Choice E has made a balance between keeping active voice and using "ing" with demonstrate. It also agrees with singular Cannon....has...so it sounds right.

My first apprehension is that this does not seem to be either an OG or GPRP topic. So I make bold to add my own slant to it.

Choice E is seems to be the OA according some, a choice that relies on cannon that shoots dead chickens for proving the utility of the exercise, forgetting that it is neither the cannon alone nor shooting alone that is helpful but the combination of a cannon and shooting dead chickens. The noun phrase ‘cannon shooting dead chickens’ is an essential requirement in the context and that is precisely the reason that the modifier is not set off from the noun by a comma.

Participles are not verbs in that they are timeless and universal. If you want to ascribe a tense, and then you have to attach an auxiliary verb to it. Hence please be confirmed that a cannon shooing dead chickens does not imply that the action is currently going on. But E, limits itself to present tense and is therefore is not as universal or comprehensive as A.

The consensus seems to lean on E but I join the A’ers.

(D) that shoots dead chickens at airplanes proves itself helpful to demonstrate
(E) that shoots dead chickens at airplanes has proved helpful in demonstrating

A,B, and C are gone- bcoz a cannon shooting dead chickens indicates that it is the present state of cannon and thats not correct.

confused between D & E.... Experts opinion..

According to United States Air Force officials, a cannon shooting dead chickens at airplanes has proved helpful to demonstrate what kind of damage can result when jets fly into a flock of large birds.

The sentence contains ing modifier without a comma so shooting dead chickens modifies cannon , there is ambiguity about what has proved helpful to demonstrate (the cannon itself or the act of shooting , it can be removed by placing a comma after the modifying clause e.g. shooting dead chickens at airplanes, has proved . . . . ) E clarifies this ambiguity by using different construction and it is clear that cannon has proved useful not the act of shooting.

Definitely A .
It is not the canons that prove to be helpful , but rather the entire act of shooting dead chickens at airplanes that proves to be helpful in demonstrating the kind of damage than can happen were a jet to fly in a flock of birds .
Canon is just one tool that helps in proving the whole point .
