1. Julia Robinson, an avid photographer in her spare time, was able to capture stunning shots of the local wildlife on her last business trip to Australia. Which of the following is an adjective in the preceding sentence?

• A. Time
• B. Capture
• C. Avid
• D. Photographer

Correct answer: C

Rationale: The correct answer is 'C: Avid.' In the sentence, 'avid' describes Julia Robinson as someone who is enthusiastic and passionate about photography in her spare time. Adjectives are words that modify or describe nouns, and in this case, 'avid' modifies the noun 'photographer.' Choice A, 'Time,' is a noun and does not describe or modify any other word in the sentence. Choice B, 'Capture,' is a verb indicating an action taken by Julia Robinson. Choice D, 'Photographer,' is a noun identifying the role or occupation of Julia Robinson, not describing her in this context.

2. What is the primary difference between ionic and metallic bonding?

• A. Ionic bonds involve electron transfer, while metallic bonds involve electron sharing.
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.

Correct answer: B

Rationale: Ionic bonds involve electron transfer, where one atom completely donates an electron to another, resulting in discrete molecules. On the other hand, metallic bonds are non-directional and strong, formed by a 'sea' of delocalized electrons shared among all metal atoms. This shared electron cloud allows for strong bonding throughout the entire material, making metallic bonds non-directional and strong compared to the directional and weaker nature of ionic bonds. Choice A is incorrect because metallic bonds do not involve electron sharing but rather the sharing of a sea of delocalized electrons. Choice C is incorrect as metallic bonds can also exist between metal atoms, not just between metals and non-metals. Choice D is incorrect because metallic bonds do not form discrete molecules but rather extended structures due to the sharing of electrons among all metal atoms.

3. What are the components of the female internal genitalia and their functions?

• A. Fallopian tubes: transport eggs from the ovaries to the uterus
• B. Vagina: serves as the birth canal and connects the uterus to the external environment
• C. Ovaries: produce eggs and hormones
• D. Cervix: serves as the lower part of the uterus connecting it to the vagina

Correct answer: C

Rationale: The correct answer is C. The ovaries are responsible for producing eggs (ova) and hormones (estrogen and progesterone). They are essential for reproduction, including the release of eggs for fertilization and for regulating the menstrual cycle. The fallopian tubes, as mentioned in choice A, transport eggs from the ovaries to the uterus for potential fertilization. The vagina, described in choice B, serves as the birth canal and also connects the uterus to the external environment. The cervix, as stated in choice D, is the lower part of the uterus that connects it to the vagina and also plays a role in protecting the uterus from infections and serving as a passage for menstrual flow.

4. Which of the following is NOT a function of the cardiovascular system?

• A. Transporting oxygen to cells
• B. Maintaining blood pressure
• C. Carrying waste products to the kidneys for removal
• D. Initiating the immune response

Correct answer: D

Rationale: The cardiovascular system is responsible for transporting oxygen to cells (A), maintaining blood pressure (B), and carrying waste products to the kidneys for removal (C). Initiating the immune response (D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen, thymus, and lymph nodes. Therefore, option D is the correct answer as it pertains to a function outside the scope of the cardiovascular system, making it the odd one out among the given choices.

5. Select the meaning of the word 'somnambulist' in the sentence based on the context clues: 'If you wake up outside in your pajamas in the middle of the night, you may be a somnambulist.'

• A. Explorer
• B. Magician
• C. Insomniac
• D. Sleepwalker

Correct answer: D

Rationale: The correct answer is 'D: Sleepwalker.' A somnambulist is someone who walks or performs other activities while asleep, commonly known as a sleepwalker. In the given sentence, the context of waking up outside in pajamas in the middle of the night indicates an occurrence associated with sleepwalking. Choice A, 'Explorer,' is incorrect as it does not relate to the behavior described. Choice B, 'Magician,' is not related to the context of sleepwalking. Choice C, 'Insomniac,' refers to a person who has difficulty falling asleep or staying asleep, which is not the meaning conveyed in the sentence. Therefore, 'D: Sleepwalker' is the most appropriate choice based on the context clues provided.
