Step 1 — Read the sentence carefully:
"Alexander Solzhepitsyn’s works will be _______ by every lover of liberal thought and they will bring home to him how restrictive freedom is in the Russian system."
The blank must be filled with a word that means "read" or "studied carefully," since the sentence talks about understanding the meaning of his works.
Step 2 — Consider the meaning of the correct word:
The word perused means to read something carefully and thoroughly, often with the intention of understanding it in depth.
Step 3 — Fit the word into the sentence:
"Alexander Solzhepitsyn’s works will be perused by every lover of liberal thought and they will bring home to him how restrictive freedom is in the Russian system."
This fits perfectly, because readers who value liberal thought would carefully read (peruse) his works to grasp the message about restrictions in Russia.
Step 4 — Conclusion:
Thus, the most appropriate word for the blank is perused.
Final Answer:
The correct option is (D) : perused.
