Concerned about the dangers posed to civil aviation by migratory birds, the national aviation administration and several wildlife protection societies have collaborated in a project aimed at monitoring flight patterns of high-flying species such as storks, herons, and geese, tightening coordination of landing and take-off times of commercial air traffic, and the training of pilots to avert and prevent collisions.

A. aimed at monitoring flight patterns of high-flying species such as storks, herons, and geese, tightening coordination of landing and take-off times of commercial air traffic, and the training of pilots to avert

B. aiming to monitor flight patterns of high-flying species such as storks, herons, and geese, tightening coordination of landing and take-off times of commercial air traffic, and the training of pilots to avert

C. aimed at monitoring flight patterns of high-flying species such as storks, herons, and geese, tightening coordination of landing and take-off times of commercial air traffic, and training pilots to avert

D. aiming to monitor flight patterns of high-flying species such as storks, herons, and geese, tightly coordinating when commercial air traffic is to take off and land, and to train pilots to avoid

E. to aim at monitoring flight patterns of high-flying species such as storks, herons, and geese, to coordinate tight landing and take-off times for commercial air traffic, but to train pilots to avert

[Reveal] Spoiler:
AC C:
This answer choice corrects the Parallelism mistake in the original question, by changing the noun the training to a non-conjugated verb training, to match the previous items in the list (monitoring, tightening coordination).

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

A list of 3 items or more, separated by commas and and/or before the last item.

In a list of 3 or more items, all the items should be the same part of speech (all nouns, all verbs, or all adjectives).

What's tricky about this list is that the noun the training has the same form as the verbs, but because of the article the (training), the V+ing form functions as a noun, and violates the parallelism.

Although this answer choice is not stylistically perfect (avert and prevent is a redundancy, as these two words mean approximately the same thing), it is the only answer choice that is grammatical, logical, and has a correct parallel structure

1. Aimed at = Idiomatically Correct
2. tightening // Training = Parallelism...

Anything I am missing ?

Answer must be (C) based on the above...

'Ed' ending word such as 'aimed' without a comma before it, will almost always refer to the noun closest to it, in this case 'project'.

Further, considering the split of aimed vs aiming, aiming. Without a preceding comma refers to the closest noun- project.

The project cannot by itself aim at doing anything!

E has to be ruled out because now we know the core of the topic is to refer to 'project'.Basically to modify 'aimed'

This leaves us with A and C.

Now tightening tells us about 'ing' modifiers. In this case clearly it seems we need a cause and effect phenomenon. So everything is fine till now. Next comes the usage of such as to introduce examples. Even this is fine in both cases.

Now 'ing' and another 'ing' should indicate parallelism. Comparing A with C, we find the use of 'the' in A, a thing that breaks the parallelism.
