1. How do you find the factors of a number?
- A. Divide the number by all possible numbers
- B. Find all pairs of numbers that multiply to give the number
- C. List all the multiples of the number
- D. Add the digits of the number together
Correct answer: B
Rationale: The correct way to find the factors of a number is to identify all pairs of numbers that, when multiplied together, result in the given number. This method allows you to determine all the factors of the number. Choice A is incorrect because dividing the number by all possible numbers is not an efficient way to find its factors. Choice C is incorrect as listing all the multiples of the number does not give the factors. Choice D is unrelated to finding factors as adding the digits of a number together does not provide information about its factors.
2. Which statement is true regarding the process of digestion?
- A. Digestion of starch begins in the mouth.
- B. Amylase is produced by the stomach to help break down food in the upper intestine.
- C. The di- and tri-saccharides produced in early digestion are absorbed through the intestinal wall.
- D. Proteases are responsible for breaking down starches.
Correct answer: A
Rationale: The statement 'Digestion of starch begins in the mouth' is correct. Salivary amylase, an enzyme produced in the salivary glands, initiates the breakdown of starch into simpler sugars like maltose in the mouth before further digestion in the stomach. This initial breakdown of starch is crucial in the digestion of carbohydrates, marking the beginning of the digestive process. Choice B is incorrect because amylase is produced in the salivary glands, not the stomach. Choice C is incorrect because di- and tri-saccharides are further broken down into monosaccharides before absorption. Choice D is incorrect because proteases are enzymes that break down proteins, not starches.
3. How many quarts are equivalent to 2 liters?
- A. 1.06 quarts
- B. 0.5 quarts
- C. 2.1 quarts
- D. 4 quarts
Correct answer: A
Rationale: To convert liters to quarts, we know that 1 liter is approximately equal to 1.06 quarts. Therefore, 2 liters would be around 2.12 quarts. However, for practical purposes, it's often rounded to 2.1 quarts. Option A, '1.06 quarts,' is the closest and most accurate approximation. Option B, '0.5 quarts,' is incorrect as it represents half of the actual conversion. Option C, '2.1 quarts,' is close but slightly higher than the actual conversion. Option D, '4 quarts,' is double the correct conversion and is therefore incorrect.
4. The realtor showed __________ and __________ a house on Wednesday afternoon. Which of the following pronoun pairs should be used in the blanks above?
- A. She, I
- B. She, me
- C. Me, her
- D. Her, me
Correct answer: D
Rationale: In the sentence, 'The realtor showed her and me a house on Wednesday afternoon,' the pronouns 'her' and 'me' are used as objects of the verb 'showed.' When choosing pronouns to fill in the blanks, it is important to use objective pronouns to maintain correct grammar and sentence structure. Choice A ('She, I') and Choice B ('She, me') are incorrect as 'I' and 'she' are subjective pronouns, not objective pronouns needed as objects in this sentence. Choice C ('Me, her') is also incorrect as the order and usage of pronouns are reversed from the correct form in the sentence.
5. 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.
