One reason some particle physicists are switching to astronomy late in their careers is that they tire of spending years constructing environments in which they can conduct experiments; astronomers have an infinite and ready-made supply of environments at their disposal.

A. One reason some particle physicists are switching to astronomy late in their careers is that they tire of spending years constructing environments in which they can conduct experiments; astronomers have an infinite and ready-made supply of environments at their disposal.

B. Late in their careers, one reason that some particle physicists are switching to astronomy is suggested by the fact that particle physicists must spend years constructing environments in which they can conduct experiments, while astronomers have an infinite and ready-made supply of environments at their disposal.

C. Late in their careers, one reason that some particle physicists are switching to astronomy is suggested by the fact that particle physicists must spend years constructing environments in which they can conduct experiments, while an infinite and ready-made supply of environments is at the disposal of astronomers.

D. The fact that particle physicists must spend years constructing environments in which they can conduct experiments while astronomers have an infinite and ready-made supply of environments at their disposal is one reason, late in their careers, some particle physicists are switching to astronomy.

E. The existence of an infinite and ready-made supply of environments at the disposal of astronomers compared with the fact that particle physicists must spend years constructing environments in which they can conduct experiments suggests one reason some particle physicists are switching to astronomy late in their careers.

the answer is A. But can anyone help me with answer A? I consider the '; '',' so I think there shold be a conjunction before astronomers

Correct modification

B. Late in their careers, one reason that some particle physicists are switching to astronomy is suggested by the fact that particle physicists must spend years constructing environments in which they can conduct experiments, while astronomers have an infinite and ready-made supply of environments at their disposal.
"Late in their careers" should modify "Particle Physicists" which is not happening here

C. Late in their careers, one reason that some particle physicists are switching to astronomy is suggested by the fact that particle physicists must spend years constructing environments in which they can conduct experiments, while an infinite and ready-made supply of environments is at the disposal of astronomers.
"Late in their careers" should modify "Particle Physicists" which is not happening here

D. The fact that particle physicists must spend years constructing environments in which they can conduct experiments while astronomers have an infinite and ready-made supply of environments at their disposal is one reason, late in their careers, some particle physicists are switching to astronomy.
The highlighted modifier is ambiguous and can modify both the phrases before and after it.

E. The existence of an infinite and ready-made supply of environments at the disposal of astronomers compared with the fact that particle physicists must spend years constructing environments in which they can conduct experiments suggests one reason some particle physicists are switching to astronomy late in their careers.
The comparison is not correct here. "The environments" are getting compared with "the fact"

IMO the answer is A because of the reasons mentioned above.

Hi ssr0623,
It is incorrect to link between two independent clauses using "comma". A conjunction is required in this case.
However, "Semicolon" can be used as a pause between two independent clauses without the need for a conjunction. Although the use of a conjunction to link between two independent clauses is generally preferred to the use of a "semicolon", the use of "semicolon" is still valid and correct "grammatically".

But a correct choice between "conjunction" and "semicolon" should be based on the context and the intended meaning by the author.
(i.e: does the author want just a pause? or does he want to emphasize a correlation or contrast or any other relations that the conjunctions function?)

Also, I advise you to see this video by GMATNinja concerning the same topic : https://www.youtube.com/watch?v=JLAJ_drP8UM

B and C are out for obvious modifier errors
Even D has a severe modifier error- the mispaced ",late in their careers,"

Between A and E, E has a comparison error. Hence only A matches our expectations and hence happens to be the winner
