1. Which of the following sentences contains a homophone error?

Correct answer: B

Rationale: The correct answer is B because 'aural' and 'oral' are homophones, but they have different meanings. 'Aural' refers to hearing, while 'oral' refers to the mouth or spoken words. In the context of treating mouth ulcers, the correct term should be 'oral paste.' Choices A, C, and D do not contain homophone errors. In choice A, 'heard' is correctly used in the context of listening. Choice C is grammatically correct and does not involve homophones. Choice D correctly uses 'effect' and does not involve homophones.

2. Which structure in the respiratory system serves as a passageway for both air and food, with a flap-like structure that prevents food from entering the trachea during swallowing?

Correct answer: B

Rationale: The pharynx is the correct answer. The pharynx is a structure in the respiratory system that serves as a passageway for both air and food. It contains a flap-like structure called the epiglottis, which prevents food from entering the trachea during swallowing by covering the opening to the trachea. The larynx, although important in the respiratory system, is located below the pharynx and contains the vocal cords. The trachea is a tube that carries air to and from the lungs, while the bronchi are the two main branches that lead from the trachea into the lungs.

3. How many grams of solid CaCO3 are needed to make 600 mL of a 35 M solution? The atomic masses for the elements are as follows: Ca = 40.1 g/mol; C = 12.01 g/mol; O = 16.00 g/mol.

Correct answer: B

Rationale: 1. First, calculate the molar mass of CaCO3 by adding the atomic masses of Ca, C, and 3 O atoms: 40.1 + 12.01 + (3 * 16.00) = 100.13 g/mol. 2. Calculate the number of moles in 600 mL of a 35 M solution: 600 mL * 35 mol/L = 21,000 mmol. 3. Convert moles to grams using the molar mass of CaCO3: 21,000 mmol * (100.13 g/mol / 1000 mmol/mol) = 2,102.73 g. 4. Therefore, you would need 19.7 g of solid CaCO3 to make 600 mL of a 35 M solution.

4. What happens to the kinetic energy of an object when its velocity is doubled?

Correct answer: C

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object according to the kinetic energy formula (KE = 0.5 * m * v^2). When the velocity is doubled, the kinetic energy increases by a factor of four (2^2), which means it doubles. Therefore, when the velocity of an object is doubled, its kinetic energy also doubles. Choice A is incorrect because kinetic energy is not constant but dependent on velocity. Choice B is incorrect because halving the velocity would result in 1/4 of the original kinetic energy. Choice D is incorrect as quadrupling the kinetic energy would occur if the velocity is squared, not the kinetic energy.

5. Which phrase best completes the definition of a memoir?

Correct answer: A

Rationale: A memoir is a historical account of a person's life written by someone who has intimate knowledge of that person's life, not necessarily by the person themselves. This distinguishes it from an autobiography, which is written by the person themselves. Memoirs are nonfictional and based on factual references, making option A the most fitting completion of the definition. Choices B, C, and D are incorrect because a memoir is not necessarily written by the person about whom it is written, it is not fictional, and it should be based on factual references to be considered a memoir.
