3. The artist (draw) ________ a picture of sunset yesterday. She (draw) ________ many pictures of sunsets in her lifetime.

In the first blank, we need to use the past simple because we have 'yesterday'. So we need the past tense of 'draw', which is 'drew'. In the second blank, because we have the phrase 'in her lifetime' we need to use the present perfect and the correct form will be 'has drawn'. Therefore, the answer is: 3. The artist drew a picture of sunset yesterday. She has drawn many pictures of sunsets in her lifetime.
