It is believed that RNA predated today's cells in evolutionary history.

Lunna [17]

The given question is incomplete. However, the complete question is given below:

Read the dependent clause.

after the conversation with her publisher, when she decided to write an autobiography

Which revision changes the dependent clause into an independent clause?

After the conversation with her publisher, because she decided to write an autobiography.

Since the conversation with her publisher, when she decided to write an autobiography.

After having the conversation with her publisher, when she decided to write an autobiography.

After the conversation with her publisher, she decided to write an autobiography.

Answer:

The correct answer is - After the conversation with her publisher, she decided to write an autobiography.

Explanation:

The revision that alters the dependent clause (incomplete thought) into an independent clause (a complete thought) is the following one:

"After the conversation with her publisher, she decided to write an autobiography."

The reason behind this is that an independent clause is a clause that expresses a complete thought and no need for other clauses to be associated.

The other options (a and b) are grammatically incorrect when presented as independent clauses, whereas D is completely okay.
