Question 6:
D. None of the above

BECAUSE
— In this situation, no use of the immune system (the system that fights off sicknesses) is being used, so we can immediately eliminate A.
— In this situation, no use of the endocrine system (the system that creates hormones) is being used, so we can immediately eliminate B and C.

Question 7:
A. Endocrine, Reproductive, Nervous

BECAUSE
— In this situation, we are definitely using the endocrine system because we are talking about hormones and the endocrine system creates hormones. We can eliminate C because the endocrine system is not included.
— In this situation, we are using the reproductive and nervous system because we talk about the ovaries and testes (reproductive) and the pituitary gland (makes hormones and testosterone) which is part of the brain and the brain is part of the nervous system. We can eliminate B because it doesn’t include these and eliminate D because A is our answer.

Question 8:
D. Integumentary, Circulatory, Immune

BECAUSE
—In this situation, we can eliminate B and C because we are not using the endocrine system (makes hormones)
