Question

Adversity always presents opportunities for introspection.( Turn into complex sentence )

Answer 1

adversity always presents opportunities because of introspection

Answer 2

The answer is:

Adversity always presents opportunities, which you can use for introspection.

Here in the modified sentence, besides principal cause a subordinate adjective clause is added for the expansion of the sentence.

However, in this conversion process the meaning of the sentence and sequence of the tense is completely maintained.

Here ‘: Adversity always presents opportunities’ is the main clause and ‘which you can use for introspection’ is the subordinate clause.
