1. How many grams are in 5 kilograms?

• A. 50,000 grams
• B. 500 grams
• C. 5,000 grams
• D. 50,000 grams

Correct answer: C

Rationale: The correct answer is C: 5,000 grams. There are 1,000 grams in a kilogram. Therefore, to convert kilograms to grams, you need to multiply the number of kilograms by 1,000. In this case, 5 kilograms is equal to 5 × 1,000 = 5,000 grams. Choices A and D are incorrect as they incorrectly multiply by 10,000 instead of 1,000. Choice B is incorrect as it divides instead of multiplies, leading to an incorrect conversion.

2. What word is best to substitute for the underlined words in the following sentence? Mr. Karnicki invited all of his relatives to visit him in the hospital.

• A. his
• B. theirs
• C. them
• D. their

Correct answer: A

Rationale: The word 'his' in the sentence is referring to Mr. Karnicki's relatives, indicating possession. Therefore, the correct substitution should maintain the possessive form. 'His' is the appropriate possessive pronoun to use in this context, ensuring clarity and coherence in the sentence structure. Choices B, C, and D are incorrect as they do not correctly convey the possessive relationship between Mr. Karnicki and his relatives.

3. How many phases are there in the process of mitosis?

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: C

Rationale: The correct answer is C: '4'. Mitosis consists of four phases: prophase, metaphase, anaphase, and telophase. These phases are crucial in the orderly division of the cell's genetic material. Choice A is incorrect because mitosis is a more complex process involving multiple phases. Choice B is incorrect as it is one phase short of the total phases in mitosis. Choice D is incorrect as mitosis does not consist of five phases.

4. Which part of the bridge was built first?

• A. Cables
• B. Roadway
• C. Sidewalks
• D. Towers

Correct answer: B

Rationale: The correct answer is B: Roadway. In the construction of the Golden Gate Bridge, as with many bridges, the roadway was built first. The roadway provides the foundation and support for the rest of the structure, allowing vehicles and pedestrians to access the bridge. The construction process typically starts with the roadway to establish a base before moving on to other components like cables, towers, and sidewalks. Therefore, the roadway is an essential initial component in bridge construction. Choices A, C, and D are incorrect because, according to the provided extract, the anchorages were built first, followed by the towers, cables, and finally, the completion of the roadway. This sequence highlights the significance of establishing the structural support before the construction of other elements of the bridge.

5. Which molecules contain only carbon, hydrogen, and oxygen?

• A. Lipids and proteins
• B. Carbohydrates and lipids
• C. Proteins and carbohydrates
• D. Nucleic acids and proteins

Correct answer: B

Rationale: Carbohydrates and lipids are the molecules that contain only carbon, hydrogen, and oxygen. Carbohydrates such as sugars and starches are made up of carbon, hydrogen, and oxygen in a ratio of 1:2:1, while lipids such as fats and oils are composed of carbon, hydrogen, and oxygen as well. Lipids typically contain more carbon and hydrogen atoms compared to oxygen atoms. Proteins contain nitrogen in addition to carbon, hydrogen, and oxygen, while nucleic acids contain phosphorus in addition to carbon, hydrogen, and oxygen. Therefore, choices A, C, and D are incorrect as they include molecules that contain elements other than carbon, hydrogen, and oxygen.
