Question

i knew, I could not afford caviar. ( make it affirmative)

Answer 1

To convert an negative statement into affirmative statement, we need to remove any presence of 'no', 'not', or 'not'. We must also note that the meaning of the statement must remain the same, because disturbing the sense will make your answer inappropriate.

Anyhow, I have converted the provided sentence and you can find it below this line.

I knew, caviar was too costly for me to afford.

In the represented statement, I have embraced the utilization of the word costly to maintain the proper meaning as in the negative statement.

Answer: "I knew, caviar was too costly for me to afford."

Answer 2

I knew, I could not afford caviar.

The above sentence is a negative sentence

Changing it into an affirmative sentence, keeping the meaning intact, it will be as follows:

I knew I could afford anything but Caviar

Caviar is a highly expensive dish and here the speaker is speaking about his/ her inability to afford Caviar.

Thus in both the sentences, the meaning of the sentence has remained same.
