1. If Latoya spends 15 minutes every day practicing her flute, how much time does she spend practicing over a period of two weeks?

• A. 1 hour 45 minutes
• B. 2 hours 30 minutes
• C. 3 hours 30 minutes
• D. 3 hours 45 minutes

Correct answer: C

Rationale: Latoya practices her flute for 15 minutes every day. In two weeks (14 days), the total time spent practicing can be calculated as 15 minutes/day * 14 days = 210 minutes. To convert 210 minutes to hours, divide by 60 (since there are 60 minutes in an hour): 210 / 60 = 3 hours 30 minutes. Therefore, Latoya spends 3 hours 30 minutes practicing her flute over a period of two weeks. Choices A, B, and D are incorrect because they do not accurately calculate the total time Latoya spends practicing over two weeks.

2. After the young mother goes shopping and spends $101.85 on groceries, $21.90 at the dry cleaners, and $42.66 at the pet store, she has $200.00 in cash. How much money would she have left after her day of shopping?

• A. $33.59
• B. $29.59
• C. $25.59
• D. $21.59

Correct answer: A

Rationale: The correct answer is A, $33.59. To find out how much money she would have left, we need to calculate the total spending by adding the amounts spent at the groceries, dry cleaners, and pet store: $101.85 + $21.90 + $42.66 = $166.41. Subtract the total spending from the initial cash amount to determine the remaining cash: $200.00 - $166.41 = $33.59. Choice B, $29.59, is incorrect as it does not accurately reflect the correct calculation. Choices C and D, $25.59 and $21.59 respectively, are also incorrect as they do not consider the correct total spending amount and subtraction from the initial cash.

3. Cells reproduce by different processes, all of which fall into what two categories?

• A. Sexual reproduction and binary fission
• B. Sexual reproduction and asexual reproduction
• C. Asexual reproduction and binary fission
• D. Asexual reproduction and mitosis

Correct answer: B

Rationale: Cells reproduce through two main processes: 'sexual reproduction and asexual reproduction.' Sexual reproduction involves the fusion of gametes to produce offspring with genetic variation, while asexual reproduction involves the production of offspring genetically identical to the parent. Choice A is incorrect because binary fission is a form of asexual reproduction, not sexual reproduction. Choice C is incorrect because it combines two forms of asexual reproduction. Choice D is incorrect because mitosis is a specific type of cell division, not a form of reproduction involving the production of offspring.

4. What is the oxidation state of the nitrogen atom in the compound NH3?

• A. -3
• B. -1
• C. +1
• D. +3

Correct answer: B

Rationale: In the compound NH3, nitrogen is bonded to three hydrogen atoms. Hydrogen is always assigned an oxidation state of +1. Since the overall charge of NH3 is zero, the oxidation state of nitrogen must be -1 to balance out the hydrogen's +1 oxidation state. Therefore, the correct oxidation state of the nitrogen atom in NH3 is -1. Choice A (-3) is incorrect because it does not account for the electronegativity of hydrogen. Choice C (+1) and Choice D (+3) are incorrect as the nitrogen atom in NH3 needs to balance the +1 oxidation state of each hydrogen atom, resulting in a total of -3 to maintain the compound's charge neutrality.

5. Which word is not spelled correctly in the context of the following sentence? The pharmacist seemed to disagree with the prescription designated by the physician.

• A. pharmacist
• B. prescription
• C. designated
• D. physician

Correct answer: B

Rationale: The word 'prescription' in the sentence is misspelled as 'proscription.' A prescription is a written order for medication or treatment provided by a healthcare professional, while a proscription means a forbidding or prohibition. The other choices (A, C, D) are all correctly spelled in the context of the sentence.
