Both C and D looks correct. I chose D over C as D is more hypothetical and a reaction of a fish to it's rival may not have happened and looks better of the two.

Upon re-reading, I realize C is better grammatically as DO should follow would and to be silent, it should be used earlier in the sentence.

Here DID is used earlier and A Fish DID not react to X as it would (DID) to Y doesn't sound right.

Waiting for OE on this.

rahul6019 - You should take care for parallel structure first. The fish is reacting to its own reflection and rival's. Both of these should create right structure.

+C

For decades mirrors have been used to trigger aggressive responses in territorial and less self-aware species such as birds or fish, but a new study revealed that in many cases the fish did not react to its own reflection as it was to a rival fish.

A. was to a
B. it reacted; just to a
C. it did to a
D. it would to a
E. its

Honestly i was looking for as it did to the reflection of a rival fish , but there is norm in comparing the reaction to its reflection to reaction to a rival fish because at te end we are comparing reactions only.

So C for me

Others do not make sense

A. was to a - Fish did not react to its own reflection as Fish was to rival fish
B. it reacted; just to a- As fish reacted; ( absolutely incomplete) ; Just to a rival fish ( what is just to doing here )
C. it did to a - CORRECT for reason mentioned above
D. it would to a - as it would to a rival fish ( its a conditional would but the study has already happened in past and the result is known )
E. its - Fish did not react to its own reflection as its rival fish ( the construction will have to entirely different to make sense out of this one .On the lines of- Fish did not react to its rival fish did

you are welcome to point the errors out .i would be grateful

Thanks

I chose C but I could see D being correct as well. For me, if you replace did with reacted, you get the answer and I assumed the did refers to reacted.

You need to understand the meaning ----- we are talking about a historical event. 2 things in past. both already happened. using would means you are comparing a past event with a hypothetical one. does not making sense. D can not be answer.

Hey guys! Thanks for posting.

My bet on this: Answer (D) "would" expresses a conditional, over that something that might happen in the future, if a condition is fullfilled. However, here we are talking about an observation in the past.
Hence, conditional is incorrect

Only posible remaining answer is (C), as it respestcs the past tense in both side of the sentence.
