1. When is a histogram preferred over a bar graph?

A. Comparison between categories
B. Frequency
C. Percentages
D. Proportions

Correct answer: B

Rationale: Histograms are specifically designed to display the frequency distribution of continuous data, showing the distribution of values over intervals or bins. On the other hand, bar graphs are used to compare different categories or discrete data points. Therefore, the correct answer is B. Choices A, C, and D are incorrect because histograms are not primarily used for comparing categories, percentages, or proportions, but rather for visualizing the distribution of frequencies within data intervals.

2. Which of the following statements represents the central idea of this passage?

A. Self-improvement classes teach work-related skills.
B. Attendance is voluntary for self-improvement classes.
C. Many different kinds of self-improvement classes are available.
D. Cooking is one type of self-improvement classes.

Correct answer: C

Rationale: The central idea of the passage is that there are many different kinds of self-improvement classes available. The passage discusses various topics such as cooking, yoga, language learning, and computer skills, emphasizing the range of options for self-improvement classes. This choice captures the main theme of the passage focusing on the diversity of available classes for personal development.

3. Which of the following structures connects muscle to bone?

A. Ligaments
B. Tendons
C. Muscles
D. Bones

Correct answer: B

Rationale: Tendons are the correct answer as they are fibrous structures that connect muscle to bone, enabling the transmission of force during movement. Ligaments, on the contrary, connect bone to bone, aiding in joint stability. Muscles contract to generate force and facilitate movement, while bones provide structural support and protect internal organs.

4. Which of the following words functions as a verb in the sentence?

A. fought
B. control
C. trade
D. those

Correct answer: A

Rationale: In the sentence, 'fought' is the only word that functions as a verb. It shows action, as it is the past tense of the verb 'fight.' The other words in the sentence do not serve as verbs in this context. 'Control' and 'trade' can also be verbs, but in this specific sentence, they are not used as verbs but as nouns. 'Those' is a pronoun and does not function as a verb.

5. Which type of muscle tissue has a unique branching network and is found in the heart?

A. Skeletal muscle
B. Cardiac muscle
C. Smooth muscle
D. Multifidus muscle

Correct answer: B

Rationale: The correct answer is B, Cardiac muscle. Cardiac muscle is the type of muscle tissue that has a unique branching network and is found in the heart. This type of muscle is involuntary and contracts rhythmically to pump blood throughout the body. Skeletal muscle, choice A, is attached to bones and is responsible for voluntary movements. Smooth muscle, choice C, is found in the walls of internal organs and blood vessels, playing a role in involuntary movements. Multifidus muscle, choice D, is a specific muscle in the back that helps with spinal stability, unrelated to the unique branching network found in cardiac muscle.
