1. What step of the scientific method must come before generating a hypothesis?

• A. Collecting and organizing data.
• B. Communicating the results in a scientific journal.
• C. Conducting an experiment.
• D. Researching previous studies for background.

Correct answer: D

Rationale: The correct answer is D, 'Researching previous studies for background.' Before formulating a hypothesis, it is essential to review existing literature, studies, and information related to the topic to understand the context and identify gaps in knowledge. This step helps researchers build on existing knowledge and formulate a clear hypothesis based on the information gathered. Choices A, B, and C are incorrect because they come after the step of researching previous studies and developing a hypothesis. Collecting and organizing data, conducting an experiment, and communicating results typically follow the hypothesis generation step in the scientific method.

2. When a patient is lying flat on their back, which of the following positions are they in?

• A. Prone.
• B. Supine.
• C. Lateral.
• D. Medial.

Correct answer: B

Rationale: When a patient is lying flat on their back, they are in the supine position. In the supine position, the person's face is facing upward, and their back is touching the surface they are lying on. This position is commonly used for medical examinations and procedures. Choice A, 'Prone,' refers to lying face down, not on the back. Choice C, 'Lateral,' indicates lying on the side. Choice D, 'Medial,' pertains to the middle or center, not a position in relation to lying on the back.

3. Water is considered a universal solvent due to its ____.

• A. Cohesion
• B. Adhesion
• C. Molarity
• D. Dilution

Correct answer: B

Rationale: The correct answer is B: Adhesion. Water's polarity allows it to dissolve many substances due to its ability to adhere to and interact with other molecules, making it an effective solvent. Cohesion refers to water molecules sticking together, molarity is a measure of concentration, and dilution refers to the process of reducing the concentration of a solute in a solution, none of which directly relate to water's role as a universal solvent.

4. How many centimeters are in 1 meter?

• A. 10 cm
• B. 100 cm
• C. 1,000 cm
• D. 10,000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. 1 meter is equivalent to 100 centimeters. Choice A (10 cm) is incorrect as it represents the conversion of decimeters to centimeters. Choice C (1,000 cm) is incorrect as it represents the conversion of meters to millimeters. Choice D (10,000 cm) is incorrect as it represents the conversion of meters to centimeters with an extra zero.

5. Identify the preposition in the following sentence: The cat jumped over the fence.

• A. cat
• B. jumped

Correct answer: C

Choice D 'the' is incorrect as it is an article.
