This is also fine. It’s natural in Japanese and ‘develop’ is translated accurately.
It can be a bit stiff, so you often see the expression in writing.
In Japanese, ‘develop’ + ‘some ability’ can be said のうりょくがつくwhich is close to the sense of ‘ gain ability.

For your information, ‘reading comprehensive’ can be translated as 読解力どっかいりょく.
