1. What is the correct name of MgO?

• A. Manganese oxide
• B. Magnesium oxide
• C. Magnesium oxate
• D. Magnesium hydroxide

Correct answer: B

Rationale: The correct name of MgO is Magnesium oxide. Mg represents the chemical symbol for magnesium, and O represents the chemical symbol for oxygen. When these elements combine, they form magnesium oxide. Option A, Manganese oxide, is incorrect as it refers to a compound of manganese and oxygen, not magnesium. Option C, Magnesium oxate, is not a valid chemical compound name. Option D, Magnesium hydroxide, refers to a different compound consisting of magnesium, oxygen, and hydrogen.

2. What word is best to substitute for the underlined word in the following sentence? Roseanne was sent to the lab to collect Roseanne’s results.

• A. she
• B. their
• C. her
• D. hers

Correct answer: C

Rationale: The correct option to substitute for 'Roseanne’s' is 'her' to maintain correct pronoun-antecedent agreement. In this case, using 'her' makes the sentence grammatically correct and clear by referring back to Roseanne in a proper manner. Choice A, 'she,' is a subject pronoun and does not match the possessive form needed in the sentence. Choice B, 'their,' is plural and does not agree with the singular possessive 'Roseanne’s.' Choice D, 'hers,' is a possessive pronoun but cannot directly replace 'Roseanne’s' in this context; 'her' is the appropriate choice to indicate possession.

3. Which word in the following sentence is a noun: 'The bird flew across the blue sky'?

• A. across
• B. flew
• C. bird
• D. blue

Correct answer: C

Rationale: In the sentence 'The bird flew across the blue sky,' 'bird' is the noun. A noun is a word that represents a person, place, thing, or idea. In this sentence, 'bird' represents a living creature, making it the noun. 'Across' is a preposition used to show the relationship between 'flew' and 'sky.' 'Flew' is a verb indicating an action, and 'blue' is an adjective describing the sky.

4. Reduce 5 & 3/4 divided by 1/2.

• A. 5 & 1/2
• B. 2 & 3/8
• C. 18
• D. 11 & 1/2

Correct answer: D

Rationale: To divide mixed numbers, convert them to improper fractions. 5 & 3/4 = 23/4 and 1/2 = 2/1. So, 23/4 ÷ 2/1 = 23/4 * 1/2 = 23/8 = 2 & 7/8. Therefore, 5 & 3/4 divided by 1/2 reduces to 11 & 1/2. Choices A, B, and C are incorrect because they do not represent the correct result of dividing 5 & 3/4 by 1/2.

5. What conclusion can be drawn about the article?

• A. The author explains differences in eating methods.
• B. Eating habits vary across different cultures.
• C. Space travel has posed challenges for eating habits.
• D. Chopsticks are more suitable than forks for space travel.

Correct answer: A

Rationale: The correct answer is A. The passage discusses different eating methods in various cultures, focusing on their differences. The author describes the development of cutlery in European cultures, the use of chopsticks in China, and how space travel has influenced eating tools for astronauts. Choice B is incorrect because the passage emphasizes the differences rather than the similarities in eating habits across cultures. Choice C is partially supported by the passage as it mentions that space travel has created new challenges for consuming food, but it is not the main conclusion of the article. Choice D is not directly supported by the passage as it discusses the challenges of using chopsticks and forks in space rather than stating that chopsticks are superior to forks.
