1. He doesn't play Ping-Pong after school. 3. morning. 2. Wednesdays. 4. Fridays.

Solution:

This section asks to complete sentences about Oscar based on Activity 1. Let's fill in the blanks using the information from the table and the Venn diagram:

• 1. He doesn't play Ping-Pong after school. (This sentence is already complete and states Oscar does not play Ping-Pong after school. Based on the table, Oscar plays the piano after school on Tuesdays.)
• 3. morning. (The sentence is incomplete. Assuming it relates to Oscar's activities, and referring to the table, Oscar plays badminton on Monday morning.)
• 2. Wednesdays. (This seems to be a day of the week without a complete sentence. If it's meant to be a sentence about Oscar, we can infer from the table that he plays the piano on Tuesdays, guitar on Thursdays, and badminton on Mondays. No activity is listed for Wednesdays for Oscar.)
• 4. Fridays. (Similar to Wednesdays, this is a day of the week without a complete sentence. The table shows Oscar playing the piano on Tuesdays, guitar on Thursdays, and badminton on Mondays. No activity is listed for Fridays for Oscar.)

Answer:

• 1. He doesn't play Ping-Pong after school. (This sentence is complete)
• 3. He plays badminton in the morning. (Assuming 'morning' refers to Monday morning and the activity is badminton as shown in the table for Oscar.)
• 2. Oscar plays gymnastics on Wednesdays. (This is an assumption as gymnastics is not explicitly mentioned for Oscar on Wednesdays in the provided table. However, if this is a fill-in-the-blank from a lesson, this is a possible completion.)
• 4. Oscar plays the piano on Fridays. (This is an assumption as the table shows Oscar playing the piano on Tuesdays and guitar on Thursdays. No activity is listed for Fridays for Oscar. However, if this is a fill-in-the-blank from a lesson, this is a possible completion.)
