1. Which of the following lists the author’s actions in the correct sequence?

• A. The author looked at the house on Forest Road, then at a house with a yard that was too small, then at two houses that were too small, and then finally at a house that was too expensive.
• B. The author looked at the house on Forest Road, then at two houses that were too small, then at a house with a yard that was too small, and then finally at a house that was too expensive.
• C. The author looked at two homes with yards that were too small, then a house with only one bathroom, then a house that was too expensive, and then finally the house on Forest Road.
• D. The author looked at two homes that were too small, then a house with a yard that was too small, then a house that was too expensive, and then finally at the house on Forest Road.

Correct answer: B

Rationale: The correct sequence of the author's actions based on the extract is as follows: the author looked at the house on Forest Road first, then two houses that were too small, followed by a house with a yard that was too small, and finally a house that was too expensive. Therefore, choice B correctly lists the author's actions in the given sequence. Choice A is incorrect as it reverses the order of the second and third houses visited. Choice C is incorrect as it includes a house with only one bathroom, which was not mentioned in the extract. Choice D is incorrect as it places the house on Forest Road last, whereas it was actually the first house visited.

2. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?

• A. Insulin
• B. Glucagon
• C. Estrogen
• D. Testosterone

Correct answer: A

Rationale: The correct answer is A: Insulin. Type 1 diabetes is characterized by the body's inability to produce insulin, the hormone responsible for regulating blood sugar levels. Insulin deficiency in type 1 diabetes leads to high blood sugar levels as the body cannot effectively utilize glucose for energy. Glucagon (Choice B) is a hormone that works opposite to insulin, raising blood sugar levels. Estrogen (Choice C) and testosterone (Choice D) are not directly involved in blood sugar control or the pathophysiology of type 1 diabetes.

3. What type of particle carries no charge and mediates the strong nuclear force between protons and neutrons?

• A. Electron
• B. Photon
• C. Gluon
• D. Neutrino

Correct answer: C

Rationale: The correct answer is C: Gluon. Gluons are the particles responsible for mediating the strong nuclear force between protons and neutrons. They are the carriers of this force. Choice A, Electron, is incorrect as electrons are negatively charged. Choice B, Photon, is incorrect as photons are chargeless particles of light. Choice D, Neutrino, is incorrect as neutrinos are neutral particles with minimal mass and weak interactions with matter, not involved in mediating the strong nuclear force between protons and neutrons.

4. What is the scientific term for a broken bone?

• A. Osteoporosis
• B. Fracture
• C. Sprain
• D. Dislocation

Correct answer: B

Rationale: The scientific term for a broken bone is a fracture. Osteoporosis is a condition characterized by weak and brittle bones, not a broken bone. A sprain involves an injury to a ligament, not a bone. Dislocation occurs when the ends of bones are forced out of their normal positions at a joint, which is different from a fracture.

5. What is the primary purpose of conducting an experiment?

• A. to test a hypothesis
• B. to collect data
• C. to identify a control state
• D. to choose variables

Correct answer: A

Rationale: The correct answer is A: 'to test a hypothesis.' The primary purpose of conducting an experiment is to test a hypothesis. This process allows researchers to gather empirical evidence to either support or refute a proposed hypothesis. By systematically manipulating variables and observing outcomes, scientists can draw conclusions about the relationships between these variables. Choice B, 'to collect data,' is a common step within an experiment, but the ultimate goal is to test a specific hypothesis. Choice C, 'to identify a control state,' is not the primary purpose but rather a methodological consideration within an experiment to ensure reliable results. Choice D, 'to choose variables,' is a step that is typically done before conducting the experiment and is not the primary purpose of the experiment itself.
