1. What is the scientific name for the tear gland?

• A. Lachrymal gland
• B. Lacrimal sac
• C. Lacrimal duct
• D. Lacrimal papilla

Correct answer: A

Rationale: The correct answer is A: Lachrymal gland. The lachrymal gland, also known as the tear gland, is the almond-shaped gland located above each eye, responsible for producing tears. Tears are a complex mixture of water, electrolytes, proteins, and other substances that help lubricate and protect the eyes from dryness and irritation. Choice B, Lacrimal sac, is incorrect as it refers to a structure that collects tears from the eye. Choice C, Lacrimal duct, is incorrect as it is the tube that carries tears from the lacrimal sac to the nasal cavity. Choice D, Lacrimal papilla, is incorrect as it is a small elevation at the inner corner of the eye where tears drain into the puncta.

2. What is the role of the diaphragm in respiration?

• A. To regulate air pressure in the lungs
• B. To contract and expand the lungs
• C. To store oxygen
• D. To break down carbon dioxide

Correct answer: B

Rationale: The correct answer is B. The diaphragm plays a crucial role in respiration by contracting and expanding the lungs. When the diaphragm contracts, it moves downward, creating more space in the chest cavity and allowing the lungs to expand. This expansion leads to a decrease in pressure inside the lungs, causing air to rush in. When the diaphragm relaxes, it moves back up, decreasing the space in the chest cavity and causing the lungs to deflate. This action increases the pressure in the lungs, leading to air being pushed out. Therefore, the diaphragm's main function is to facilitate the inhalation and exhalation of air by contracting and expanding the lungs. Choices A, C, and D are incorrect because the diaphragm's primary function is not to regulate air pressure in the lungs, store oxygen, or break down carbon dioxide. Instead, its main purpose is to aid in the mechanical process of breathing.

3. Why was Lamarr's invention not of interest to the US?

• A. Hollywood was known to have spies
• B. The navy preferred to use the work of military engineers
• C. The military was too preoccupied to consider new inventions
• D. They suspected her patent was invalid

Correct answer: B

Rationale: The correct answer is B. The US Navy preferred to utilize technology developed by military engineers rather than consider Lamarr's invention. Choice A is incorrect because Hollywood containing spies is not relevant to why the US was not interested in Lamarr's invention. Choice C is incorrect as there is no mention of the military being too preoccupied to consider new inventions in the provided context. Choice D is incorrect as there is no indication that the US suspected Lamarr's patent to be invalid; rather, the focus was on the navy's preference for technology developed by military engineers.

4. Which option best describes the use of the spider in the poem?

• A. Idiom
• B. Haiku
• C. ABBA rhyming convention
• D. Simile

Correct answer: D

Rationale: The correct answer is D, 'Simile.' In the poem, the speaker compares the spider to an artist using 'as,' indicating a simile. A simile is a figure of speech that compares two different things using 'like' or 'as.' Choices A, B, and C are incorrect. An idiom is a phrase with a figurative meaning different from its literal meaning, a haiku is a form of Japanese poetry, and ABBA rhyming convention refers to a specific rhyme scheme commonly found in poetry, none of which apply to the comparison of the spider to an artist in the poem.

5. What is the unit of measurement for density?

• A. Grams per liter (g/L)
• B. Kilograms per cubic meter (kg/m³)
• C. Pounds per square inch (psi)
• D. Newtons per meter (N/m)

Correct answer: A

Rationale: Density is defined as mass per unit volume. The most commonly used unit for density in the metric system is grams per liter (g/L). Kilograms per cubic meter (kg/m³) is also a common unit for density, but grams per liter is more frequently used in everyday measurements. Pounds per square inch (psi) is a unit of pressure, not density. Newtons per meter (N/m) is a unit of force per unit length, not density.
