- A. Creates a sense of mystery.
- B. Emphasizes the large size of the house.
- C. Suggests the house is in poor condition.
- D. Implies the house is haunted.
Correct answer: C
Rationale: The word "dilapidated" specifically describes the house's deteriorating state.
2. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."
- A. "My biggest fear"
- B. "that I wouldn't live life to the fullest"
- C. "life"
- D. "the fullest"

3. The microscopic units responsible for muscle contraction are called
- A. Neurons
- B. Myofibrils
- C. Tendons
- D. Sarcomeres
Correct answer: D
Rationale: The correct answer is D: Sarcomeres. Sarcomeres are the fundamental contractile units of skeletal muscle. They are composed of overlapping actin and myosin filaments that slide past each other during muscle contraction, resulting in muscle shortening. Neurons (A) are nerve cells that transmit signals to and from the brain. Myofibrils (B) are thread-like structures within muscle fibers that contain sarcomeres. Tendons (C) are fibrous connective tissues that attach muscles to bones, but they are not directly involved in muscle contraction like sarcomeres are.
4. Two cars with different masses collide head-on. Which car experiences a greater change in momentum?
- A. The car with the larger mass
- B. The car with the smaller mass
- C. Both cars experience the same change in momentum
- D. It depends on the initial velocities of the cars
Correct answer: B
Rationale: The car with the smaller mass. Although momentum is conserved in the collision, the change in momentum is inversely proportional to mass. Therefore, the car with the smaller mass will experience a larger relative change.
5. What is the term for the time it takes for a wave to complete one full cycle?
- A. Frequency
- B. Amplitude
- C. Period
- D. Wavelength
Correct answer: c
Rationale: The period of a wave is the time taken for one complete oscillation or cycle.
6. The human immunodeficiency virus (HIV) targets and destroys which type of immune cell?
- A. Neutrophils
- B. Macrophages
- C. Helper T cells
- D. Memory B cells
Correct answer: A
Rationale: The correct answer is C: Helper T cells. HIV targets and destroys Helper T cells, which are a crucial component of the immune system responsible for coordinating the immune response. Neutrophils and macrophages are also important immune cells, but they are not the primary target of HIV. Memory B cells are responsible for mounting a rapid response upon re-exposure to a pathogen but are not the main target of HIV. Thus, HIV primarily affects Helper T cells, leading to the weakening of the immune system and the development of acquired immunodeficiency syndrome (AIDS).
