1. Which sentence uses parallel structure correctly?
- A. I enjoy reading, watching movies, and spending time with friends.
- B. Reading, watching movies, and spending time with friends are all activities I enjoy.
- C. I like to read, watch movies, and spend time with friends.
- D. Reading, movies, and friends are all things I enjoy.
Correct answer: B
Rationale: Parallel structure means using the same grammatical form for elements in a list. Option (B) uses parallel gerunds ('reading,' 'watching,' 'spending'), making it the correct choice. The other options have inconsistencies in the form of the listed activities, making them grammatically incorrect. Option (A) starts with 'I enjoy' but then switches to '-ing' verbs. Option (C) changes from 'like' to '-ing' verbs, breaking parallelism. Option (D) lists 'reading' correctly but then switches to singular nouns ('movies,' 'friends'), which is not parallel.
2. What is the first number in a blood pressure reading?
- A. Diastolic pressure
- B. Mean arterial pressure
- C. Pulse rate
- D. Systolic pressure
Correct answer: D
Rationale: The correct answer is D: Systolic pressure. In a blood pressure reading, the first number represents the systolic pressure, which is the maximum pressure in the arteries during heart contraction. The second number in the reading is the diastolic pressure, which indicates the pressure in the arteries when the heart is at rest. Choices A, B, and C are incorrect because diastolic pressure, mean arterial pressure, and pulse rate are not the first numbers in a blood pressure reading.
3. What is 2.7834 rounded to the nearest tenth?
- A. 2.7
- B. 2.78
- C. 2.8
- D. 2.88
Correct answer: C
Rationale: To round 2.7834 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is greater than or equal to 5, the digit in the tenths place is rounded up. Therefore, 2.7834 rounded to the nearest tenth is 2.8. Choice A (2.7) is incorrect because rounding down would require the digit in the hundredths place to be less than 5. Choice B (2.78) is incorrect because rounding to the nearest tenth involves considering the digit in the hundredths place. Choice D (2.88) is incorrect as it goes beyond rounding to just the nearest tenth.
4. Which organ system is most responsible for maintaining control of body temperature?
- A. The skeletal system.
- B. The circulatory system.
- C. The immune system.
- D. The muscular system.
Correct answer: B
Rationale: The circulatory system is the correct answer as it plays a crucial role in maintaining control of body temperature through a process called thermoregulation. Blood vessels near the skin surface dilate to dissipate heat when the body is too warm and constrict to reduce heat loss when it's too cold. Additionally, the circulatory system helps distribute heat produced from metabolic processes throughout the body to keep a stable internal temperature. The skeletal system provides structural support, the immune system defends against pathogens, and the muscular system is responsible for movement, but they are not primarily involved in regulating body temperature.
5. What type of bond connects sugar and phosphate in DNA?
- A. Hydrogen
- B. Ionic
- C. Covalent
- D. Overt
Correct answer: C
Rationale: The correct answer is Covalent (C). In DNA, a covalent bond connects sugar and phosphate molecules. This bond involves the sharing of electron pairs between the atoms, providing stability to the DNA structure. Hydrogen bonds are important in DNA structure but are not the primary bond connecting sugar and phosphate. Ionic bonds involve the transfer of electrons, and 'overt' is not a term related to the bond connecting sugar and phosphate in DNA.
