1. Which of the following uses a conjunction to combine the sentences below so the focus is on puppies requiring a lot of work? 'Puppies are fun-loving animals. They do require a lot of work.'

• A. Puppies are fun-loving animals; they do require a lot of work.
• B. Puppies are fun-loving animals, so they do require a lot of work.
• C. Since puppies are fun-loving animals, they do require a lot of work.
• D. Although puppies are fun-loving animals, they do require a lot of work.

Correct answer: D

Rationale: The correct answer is 'D' because the conjunction 'Although' conveys contrast and shifts the focus to emphasize that puppies require a lot of work despite being fun-loving. Choice A uses a semicolon, which does not emphasize the contrast needed in the context. Choice B introduces a causal relationship, not the intended contrast. Choice C uses 'Since,' which implies a causal connection rather than the desired contrast, making it incorrect.

2. What is the responsibility of the somatic nervous system?

• A. Breathing
• B. Thought
• C. Movement
• D. Fear

Correct answer: C

Rationale: The somatic nervous system is responsible for controlling voluntary movements of skeletal muscles. This system communicates sensory information and controls voluntary movements, such as walking or reaching for objects. Breathing is primarily regulated by the autonomic nervous system, which functions involuntarily. Thought processes involve complex interactions between various regions of the brain and are not directly controlled by the somatic nervous system. Fear is an emotional response that involves the limbic system of the brain and the autonomic nervous system, not the somatic nervous system.

3. Which of the following sentences is grammatically correct?

• A. Krista was not sure who to hold responsible for the broken window.
• B. Krista was not sure whom was responsible for the broken window.
• C. Krista was not sure whom to hold responsible for the broken window.
• D. Krista was not sure on who she should place responsibility for the broken window.

Correct answer: C

Rationale: The correct structure is 'whom to hold responsible' as 'whom' is the object of the verb 'to hold.' In choice A, 'who' should be 'whom' to indicate the object of the verb. Choice B is incorrect as 'whom' is incorrectly placed before 'was responsible.' Choice D is also incorrect due to the awkward phrasing and the use of 'on' which is unnecessary.

4. What determines the defining characteristic of an element?

• A. Neutrons in its nucleus
• B. Electrons surrounding the nucleus
• C. Protons in its nucleus
• D. All of the above

Correct answer: C

Rationale: The defining characteristic of an element is determined by the number of protons in its nucleus, which is referred to as the atomic number. The number of protons uniquely identifies an element. The correct answer is choice C because the number of protons in the nucleus of an atom defines its elemental identity, as different elements have a unique number of protons. Neutrons and electrons do play essential roles in the atom, but they do not determine the defining characteristic of an element. Neutrons contribute to the stability of the nucleus and isotopes of an element, while electrons are involved in chemical bonding and the reactivity of an atom.

5. Which hormone is responsible for lowering blood sugar levels?

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

Correct answer: B

Rationale: Insulin is the hormone responsible for lowering blood sugar levels. It is produced by the pancreas and facilitates the entry of glucose into cells, thereby reducing blood sugar levels. Glucagon, adrenaline, and cortisol have roles in increasing blood sugar levels through various mechanisms. Glucagon raises blood sugar levels by stimulating the liver to release stored glucose, adrenaline increases blood sugar in fight-or-flight responses, and cortisol raises blood sugar levels as part of the stress response. Therefore, in the context of lowering blood sugar levels, insulin is the correct answer.
