52.
Your Answer is
Correct Answer is F
Explanation
This sentence means that "he searched countless furniture and fabrics of that period, recording the color, texture and design", so the judgment of F is correct.
According to the semantics, the color, texture, and design here are not in parallel with the previous content, so item J is wrong.
The attributive clause guided by "preposition+which" in item G needs a subject after it, and the subject cannot be lost, so item G has a grammatical error.
There is no causal relationship before and after item H.
