1. What must you always use in all math?

• A. PEMDAS
• B. Variables
• C. Conversion factors
• D. Estimation

Correct answer: A

Rationale: The correct answer is A: PEMDAS. PEMDAS stands for the order of operations: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). It is a fundamental rule to follow in mathematics to ensure calculations are done correctly. Choices B, C, and D are incorrect as they do not encompass the essential rule that PEMDAS provides for solving mathematical expressions.

2. Which of the following organelles is responsible for producing ATP in the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosome

Correct answer: B

Rationale: Mitochondria are the powerhouse of the cell and are responsible for producing ATP through cellular respiration. ATP, or adenosine triphosphate, is the energy currency of the cell that is essential for various cellular processes. The Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion. The nucleus is responsible for housing the cell's genetic material and controlling cell activities. Ribosomes are involved in protein synthesis. However, the actual production of ATP occurs in the mitochondria through processes like the citric acid cycle and oxidative phosphorylation.

3. What is 0.5 liters to milliliters?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: The question asks for the conversion of 0.5 liters to milliliters. The correct answer is 500 ml, which is derived from the standard conversion factor where 1 liter is equal to 1000 milliliters. Choice B, 50 ml, is incorrect as it represents the conversion of 0.05 liters to milliliters. Choice C, 5 ml, is incorrect as it corresponds to the conversion of 0.005 liters to milliliters. Choice D, 0.5 ml, is incorrect as it is the same value given in the question but in milliliters.

4. Which of the following sentences uses correct punctuation?

• A. Carole is not currently working; her focus is on her children at the moment.
• B. Carole is not currently working, and her focus is on her children at the moment.
• C. Carole is not currently working; her focus is on her children at the moment.
• D. Carole is not currently working, her focus is on her children at the moment.

Correct answer: A

Rationale: Option A uses correct punctuation by correctly utilizing the semicolon to separate two closely related independent clauses. This punctuation choice effectively conveys the relationship between the two ideas presented in the sentence. Choice B is incorrect because it uses a comma without a coordinating conjunction to join two independent clauses. Choice C is incorrect as it lacks the coordinating conjunction 'and' after the comma to connect the two independent clauses. Choice D is incorrect because it lacks any punctuation or conjunction to properly separate the two independent clauses, leading to a run-on sentence.

5. Which version of the sentence is correct grammatically?

• A. I had seen her before, but yesterday was the first time I saw her indoors.
• B. I had saw her before, but yesterday was the first time I seen her indoors.
• C. I had seen her before, but yesterday was the first time I seen her indoors.
• D. I had saw her before, but yesterday was the first time I saw her indoors.

Correct answer: A

Rationale: The correct sentence is: 'I had seen her before, but yesterday was the first time I saw her indoors.' In this sentence, the correct past participle form of 'see' is used, which is 'seen' in the past perfect tense ('I had seen') and 'saw' in the simple past tense ('I saw'). Choices B, C, and D contain incorrect past participle and past tense forms of the verb 'see,' making them grammatically incorrect. Choice A is the only option that uses the correct past participle 'seen' and the correct simple past tense 'saw.' Therefore, it is the grammatically correct version of the sentence.
