1. Add 6 & 3/4 + 8 & 1/6.

• A. 35/6
• B. 14 & 2/5
• C. 14 & 11/12
• D. 12 & 3/24

Correct answer: C

Rationale: To add mixed numbers, first add the whole numbers together, then add the fractions. 6 + 8 = 14. For the fractions: 3/4 + 1/6 = (18 + 4) / 24 = 22/24 = 11/12. Therefore, 6 & 3/4 + 8 & 1/6 equals 14 & 11/12. Choice A is incorrect as it does not represent the correct sum. Choice B is incorrect because it does not match the correct result. Choice D is incorrect as it simplifies to 12 & 1/6, not 12 & 3/24.

2. If Randy sells 8 times as many vacuum cleaners as Janice, and Janice sells 690 vacuum cleaners per year, on average, how many does Randy sell each month?

• A. 4,600
• B. 5,520
• C. 6,400
• D. 8,320

Correct answer: B

Rationale: If Janice sells 690 vacuum cleaners per year, Randy sells 8 times that amount, which is 690 x 8 = 5,520 vacuum cleaners per year. To find out how many Randy sells each month, you divide 5,520 by 12 (months), which equals 460 vacuum cleaners per month. Therefore, Randy sells 5,520 vacuum cleaners per year divided by 12 months, which equals 460 vacuum cleaners per month. Choices A, C, and D are incorrect as they do not reflect the correct calculation based on the information provided.

3. The ankle bone may be called the ___________.

• A. talus
• B. talon
• C. fascia
• D. fascine

Correct answer: A

Rationale: The ankle bone is commonly known as the talus, which is a prominent bone in the human foot that forms the lower part of the ankle joint. It plays a crucial role in supporting body weight and allowing the foot to move in various directions. The terms talon and fascine are not accurate when referring to the ankle bone. Talon usually refers to the claw of a bird or animal, while fascine is a bundle of sticks used in construction or military engineering. Fascia, on the other hand, is a band of connective tissue and not a bone.

4. Which hormone is produced by the pancreas to lower blood glucose levels?

• A. Glucagon
• B. Insulin
• C. Cortisol
• D. Melatonin

Correct answer: B

Rationale: The correct answer is B: Insulin. Insulin, produced by the pancreas, is the hormone responsible for lowering blood glucose levels. It achieves this by promoting the uptake of glucose into cells, thereby reducing the concentration of glucose in the bloodstream. Choice A, Glucagon, is actually a hormone produced by the pancreas that works to raise blood glucose levels by stimulating the liver to release stored glucose. Choice C, Cortisol, is a hormone produced by the adrenal glands, not the pancreas, and is involved in stress response and regulation of metabolism. Choice D, Melatonin, is a hormone produced by the pineal gland that regulates sleep-wake cycles and is not directly involved in blood glucose level regulation.

5. Which two elements are most alike in reactivity?

• A. He and H
• B. K and Ar
• C. Cl and P
• D. Ba and Mg

Correct answer: C

Rationale: Chlorine (Cl) and Phosphorus (P) are most alike in reactivity among the given pairs. Both elements are nonmetals and belong to Group 7 (halogens) and Group 15 (nitrogen group), respectively. They have similar electronic configurations and can form compounds by gaining or sharing electrons. Chlorine is highly reactive and can easily form ionic compounds, while phosphorus also shows a range of reactivity in its compounds. Choice A (He and H) is incorrect because helium (He) is a noble gas and hydrogen (H) is a nonmetal, so they are not similar in reactivity. Choice B (K and Ar) is incorrect as potassium (K) is a metal and argon (Ar) is a noble gas, having different reactivities. Choice D (Ba and Mg) is incorrect because barium (Ba) and magnesium (Mg) are both metals, but their reactivities differ due to their positions in the periodic table.
