The correct Answer is:
To determine the conditions under which the statement "Ananya is beautiful and 165 centimetres tall" is true, we can break down the problem step by step. ### Step 1: Define the Statements Let: - \( p \): "Ananya is beautiful" - \( q \): "Ananya is 165 centimetres tall" ### Step 2: Understand the Logical Operation The statement "Ananya is beautiful and 165 centimetres tall" can be represented as \( p \land q \) (p and q). This means both conditions must be true for the entire statement to be true. ### Step 3: Analyze the Truth Values To analyze when \( p \land q \) is true, we can create a truth table for the two statements \( p \) and \( q \). The truth table will have the following combinations of truth values: | \( p \) | \( q \) | \( p \land q \) | |---------|---------|------------------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 | ### Step 4: Determine Conditions for Truth From the truth table: - The statement \( p \land q \) is true only when both \( p \) and \( q \) are true (i.e., when Ananya is both beautiful and 165 centimetres tall). ### Conclusion The statement "Ananya is beautiful and 165 centimetres tall" is true if and only if both \( p \) and \( q \) are true. Therefore, the conditions under which the statement is true are: - Ananya is beautiful (true) - Ananya is 165 centimetres tall (true) ### Final Answer The statement is true if both conditions \( p \) and \( q \) are true. ---
