1. The author's attitude towards history seems to be

• A. indifferent and neutral, presenting it as an objective field of study.
• B. critical and dismissive, questioning its practical applicability in the present.
• C. enthusiastic and optimistic, highlighting its potential to guide the future.
• D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.

2. The control center of the cell, containing genetic information (DNA), is the:

• A. Golgi apparatus
• B. Ribosome
• C. Nucleus
• D. Endoplasmic reticulum

Correct answer: C

Rationale: The correct answer is C: Nucleus. The nucleus is the control center of the cell as it contains the cell's genetic material, DNA. It acts as the brain of the cell, regulating gene expression and controlling cell activities. The Golgi apparatus is responsible for packaging and processing proteins, the ribosomes are involved in protein synthesis, and the endoplasmic reticulum is essential for protein and lipid synthesis. However, none of these organelles house the genetic information of the cell, making the nucleus the correct answer in this case.

3. Which sentence uses parallel structure correctly?

• A. I enjoy reading, watching movies, and to spend time with friends.
• B. Reading, watching movies, and spending time with friends are all activities I enjoy.
• C. 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.

4. Which of the following is NOT a function of the endocrine system?

• A. Regulating growth and development
• B. Maintaining blood sugar levels
• C. Controlling mood and emotions
• D. Facilitating digestion through muscle contractions

Correct answer: D

Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions. Option D, facilitating digestion through muscle contractions, is actually a function of the muscular and digestive systems, not the endocrine system. The endocrine system primarily regulates growth and development, maintains blood sugar levels through hormones like insulin and glucagon, and also plays a role in controlling mood and emotions through hormones such as serotonin and cortisol. Therefore, option D is correct as it is not a function directly associated with the endocrine system.

5. She decides to illustrate the organizational structure. Which of the following elements is

• A. Level of authority
• B. Lines of communication
• C. Span of control
• D. Unity of direction

Correct answer: D

Rationale: The correct answer is D, 'Unity of direction.' In the context of illustrating organizational structure, unity of direction refers to the concept that activities within an organization should be directed towards a common goal. It ensures that all efforts are aligned and coordinated towards achieving the organization's objectives. This element helps in avoiding conflicts and confusion by providing clarity and focus on the overall mission of the organization, which is essential for effective organizational performance. Level of authority, lines of communication, and span of control are important elements in organizational structure as well, but in this scenario, unity of direction specifically pertains to the coordination and alignment of activities towards a common purpose.

6. Which of the following is the main function of the stomach?

• A. To store food and break it down into smaller pieces
• B. To absorb nutrients into the bloodstream
• C. To produce enzymes that help digest food
• D. To eliminate waste products from the body

Correct answer: A

Rationale: Rationale: The main function of the stomach is to store food that has been ingested and mechanically break it down into smaller pieces through the process of churning and mixing with gastric juices. This mechanical breakdown, along with the action of stomach acid and enzymes, helps to initiate the digestion of food before it moves on to the small intestine for further digestion and absorption of nutrients. Absorption of nutrients into the bloodstream primarily occurs in the small intestine, not the stomach. The production of enzymes that help digest food primarily occurs in the pancreas and small intestine, not the stomach. The elimination of waste products from the body primarily occurs through the large intestine and rectum, not the stomach.
