1. Ventral refers to which part of the body?

• A. Top
• B. Bottom
• C. Front
• D. Back

Correct answer: C

Rationale: Ventral refers to the front part of the body or an organ. It is the opposite of dorsal, which refers to the back part. So, when describing the direction or location of an anatomical structure, ventral would mean towards the front. Therefore, the correct answer is 'Front.' Choices A, B, and D are incorrect because 'Top' refers to superior, 'Bottom' refers to inferior, and 'Back' refers to dorsal, not ventral.

2. What is the meaning of the word 'established' as used in the first paragraph?

• A. Created
• B. Ascertained
• C. Founded
• D. Reputable

Correct answer: C

Rationale: In this context, 'established' means 'founded' or set up for a long time. The word is used to indicate that phototherapy has been a recognized and in place form of medicine for over a century. 'Created' (choice A) is incorrect as it implies the initial invention of phototherapy, which is not the intended meaning here. 'Ascertained' (choice B) means to find out for certain, which does not match the context of how phototherapy has been practiced. 'Reputable' (choice D) means having a good reputation, which is not the same as being long-standing or founded.

3. What charge do Group VA elements typically have?

• A. -1
• B. -2
• C. -3
• D. 0

Correct answer: C

Rationale: Group VA elements, also known as Group 15 elements, typically have a charge of -3. This is because they have five valence electrons and tend to gain three electrons to achieve a stable octet configuration, resulting in a -3 charge. Choice A (-1) and Choice B (-2) are incorrect because Group VA elements need to gain three electrons to reach a stable electron configuration, not just one or two. Choice D (0) is also incorrect because Group VA elements do not lose electrons to form a charge of 0.

4. Which element has the highest atomic number?

• A. Uranium
• B. Hydrogen
• C. Radon
• D. Bismuth

Correct answer: A

Rationale: The correct answer is Uranium. The atomic number represents the number of protons in an atom's nucleus. Among the options provided, Uranium has the highest atomic number, which is 92. Hydrogen has an atomic number of 1, Radon has an atomic number of 86, and Bismuth has an atomic number of 83. Therefore, Uranium is the element with the highest atomic number in the given choices.

5. Change 0.004 to a ratio.

• A. 1:250
• B. 17:40
• C. 9:20
• D. 20:40

Correct answer: A

Rationale: To convert 0.004 to a ratio, first express it as a fraction. 0.004 = 4/1000 = 1/250. Therefore, the ratio is 1:250. Choice A is the correct answer. Choices B, C, and D are incorrect ratios as they do not represent the equivalent fraction of 0.004.
