1. What is molarity a measure of in a solution?

• A. Volume of the solvent
• B. Amount of solute
• C. Concentration of solute
• D. Temperature of the solution

Correct answer: C

Rationale: Molarity is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute per liter of solution. Molarity is not a measure of the volume of the solvent (choice A), the amount of solute (choice B), or the temperature of the solution (choice D). Therefore, the correct answer is the concentration of solute (choice C) as molarity specifically quantifies the solute concentration in a solution.

2. What is the term for the time it takes for a wave to complete one full cycle?

• A. Frequency
• B. Amplitude
• C. Period
• D. Wavelength

Correct answer: C

Rationale: The period of a wave is the time it takes for one complete cycle to occur. It is the duration between two successive points in the wave that are in the same phase. Frequency, on the other hand, refers to the number of cycles of a wave that occur in a given time period. Amplitude represents the maximum displacement of a wave from its equilibrium position. Wavelength is the distance between two consecutive points on a wave that are in phase. Therefore, the correct answer is 'Period' as it specifically refers to the time taken for a wave to complete one full cycle, distinguishing it from the other choices which represent different properties of a wave.

3. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C correctly places the participle phrase 'Reading the book' directly in front of the subject 'I,' ensuring that there is no dangling modifier. This structure establishes a clear connection between the action described in the introductory phrase and the subject performing the action, resulting in a grammatically correct sentence. Choice A, B, and D have dangling modifiers. In choice A, the phrase 'Walking down the street' should be followed by the noun it is describing to avoid the dangling modifier. Choice B has a dangling modifier as 'Having finished the report' does not have a clear subject to relate to. Choice D also has a dangling modifier as 'Exhausted from the hike' is not properly connected to the subject in the sentence.

4. What is an actuary?

• A. A doctor who works in a hospital.
• B. The same as a hospitalist.
• C. An insurance agent who works in a hospital.
• D. A person who assesses insurance risks and premiums.

Correct answer: D

Rationale: An actuary is a person who assesses insurance risks and premiums. This is the primary role of an actuary, involving the analysis of financial consequences of risk. Choice A is incorrect as actuaries are not medical professionals. Choice B is incorrect as a hospitalist is a physician who works in a hospital, not related to actuarial work. Choice C is incorrect as actuaries are not insurance agents; they focus on risk assessment and not sales.

5. How many daughter cells are formed from one parent cell during meiosis?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: D

Rationale: During meiosis, one parent cell produces four genetically distinct daughter cells. This occurs through two rounds of cell division, resulting in four haploid cells with half the number of chromosomes as the parent cell. Each daughter cell is genetically unique due to processes like crossing over and independent assortment during meiosis. Choice A is incorrect because meiosis results in multiple daughter cells. Choice B is incorrect because meiosis yields more daughter cells. Choice C is incorrect because meiosis produces four, not three, daughter cells.
