1. A set of integers can be classified as positive, negative, or zero. Which of the following statements about multiplying positive and negative integers is ALWAYS true?

Correct answer: B

Rationale: Rationale: When multiplying a positive integer by a negative integer, the product will always be negative. This is a fundamental rule of arithmetic. The sign of the product is determined by the rule that states that a positive number multiplied by a negative number results in a negative number. Therefore, the statement that the product will always be negative is always true when multiplying positive and negative integers.

2. Rectangle: A picture frame measures 15cm by 20cm. What is its perimeter?

Correct answer: C

Rationale: Add the lengths of all sides: perimeter = 2 (length + width) = 2 (15cm + 20cm) = 65cm.

6. Which term describes the ability of a muscle to return to its original length and shape after being stretched or contracted?

Correct answer: b

Rationale: The correct answer is B: "Elasticity." Elasticity is the term that describes the ability of a muscle to return to its original length and shape after being stretched or contracted. Contractility refers to the muscle's ability to contract forcefully, extensibility is the ability of a muscle to be stretched without being damaged, and excitability is the ability of a muscle to respond to stimuli. In this context, elasticity specifically pertains to the muscle's ability to bounce back to its original form, making it the most appropriate term in relation to the question.
