Question 6.

Let us try to break the sentence down and interpret its meaning:

“The enrichments of literary and intellectual language led to an altered understanding of the meanings that underlie time-honored expressions and traditional catchwords.”

In simple words |Enrichments of language| led to |change in understanding| of | time-honoured expressions|. 

In the context of the passage, the line means that when the terms related to 'the unconscious' were coined, they enriched the vocabulary of the language and this, in turn, changes the meanings of many old expressions related to this term.

Option D comes the closest in capturing the meaning, and hence, is the answer.

B: The meanings of the catchwords were altered. They were not enriched. Can be eliminated.

C: The catchwords did not cause a change. Their own meaning was changed. Can be eliminated.
