1. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?

• A. Unprotected sexual contact
• B. Sharing contaminated needles
• C. Deep kissing
• D. Mother to child during childbirth

Correct answer: C

Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.

2. Which of the following best describes a balanced force acting on an object?

• A. The object remains at rest
• B. The object moves with constant velocity
• C. The object accelerates
• D. The object's mass changes

Correct answer: b

Rationale: When balanced forces act on an object, the object remains in a state of constant velocity (including at rest).

3. Which of the following conclusions of Ms. Castro about leadership characteristics is TRUE?

• A. There is a high correlation between the communication skills of a leader and the ability to get
• B. A manager is effective when he has the ability to plan well.
• C. Assessment of personal traits is a reliable tool for predicting a manager’s potential.
• D. There is good evidence that certain personal qualities favor success in managerial role.

Correct answer: A

Rationale: The correct answer is A because effective communication skills are essential for a leader to successfully convey ideas, motivate teams, and build relationships. Strong communication skills enable a leader to articulate goals clearly, listen to feedback, and resolve conflicts efficiently. This correlation between communication skills and leadership effectiveness has been well-documented in numerous studies. In contrast, options B, C, and D are not universally true statements about leadership characteristics. While planning skills and personal traits may contribute to effective leadership, they are not as directly linked to leadership success as communication skills. Therefore, option A is the most accurate conclusion about leadership characteristics among the choices provided.

4. What phenomenon explains the bending of light as it passes around an obstacle or through an aperture?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Dispersion

Correct answer: c

Rationale: Diffraction refers to the bending of light waves as they encounter an obstacle or pass through an aperture, causing the light to spread out.

5. What is the unit of measurement for force in the International System of Units (SI)?

• A. Newton (N)
• B. Kilogram (kg)
• C. Joule (J)
• D. Meter per second squared (m/s²)

Correct answer: a

Rationale: Force is measured in Newtons (N) in the SI system.

6. Antibodies, crucial for immune defense, are produced by:

• A. Neutrophils
• B. Lymphocytes
• C. Monocytes
• D. Basophils

Correct answer: B

Rationale: The correct answer is B: Lymphocytes. Antibodies, also known as immunoglobulins, are produced by B lymphocytes (B cells) as a key component of the adaptive immune response. These specialized cells play a crucial role in recognizing and neutralizing pathogens, thereby providing immunity against infections. Neutrophils (A) are a type of white blood cell involved in innate immunity and phagocytosis. Monocytes (C) are another type of white blood cell that can differentiate into macrophages, which are important in phagocytosis and antigen presentation. Basophils (D) are involved in allergic responses and inflammation through the release of histamine. Lymphocytes, particularly B cells, are primarily responsible for antibody production in response to pathogens and foreign substances.
