1. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

Correct answer: B

Rationale: Chlamydia is the correct answer because if left untreated, it can lead to serious complications such as pelvic inflammatory disease (PID) in women and epididymitis in men, both of which can cause infertility. Chlamydia is a common sexually transmitted infection that often presents with no symptoms, making it important for individuals to get tested regularly, especially if they are sexually active. It is crucial to detect and treat Chlamydia early to prevent long-term consequences such as infertility. Human papillomavirus (HPV) can lead to genital warts and certain types of cancer but is not typically associated with infertility. Gonorrhea and syphilis can cause serious health problems if untreated, but infertility is more commonly associated with Chlamydia.

2. A researcher wants to conduct qualitative research. Which method should they use?

Correct answer: A

Rationale: Qualitative research focuses on gathering non-numerical, descriptive data to explore experiences, behaviors, or perspectives. Collecting patient narratives aligns with qualitative research as it involves capturing detailed accounts of individuals' experiences or viewpoints. Choices B, C, and D involve more quantitative approaches by focusing on measurable quantities, observations, or structured note-taking, which are not characteristic of qualitative research methods.

3. When is work done on an object?

Correct answer: C

Rationale: Work is done on an object whenever a force causes displacement in the object's position. According to the work-energy principle, work is calculated as the force applied multiplied by the distance the object moves in the direction of the force. Therefore, work can occur whenever there is a force exerted on the object resulting in displacement, regardless of whether the object's velocity changes or it is lifted vertically. Choice A is incorrect because work can be done even without a change in velocity. Choice B is incorrect as work requires both force and displacement, not just the application of force. Choice D is incorrect because work is not limited to vertical lifting; it can happen in any direction as long as there is a force causing displacement.

4. What is the function of white blood cells?

Correct answer: B

Rationale: White blood cells play a crucial role in the immune system by fighting infection and protecting the body from foreign invaders. Choice A, 'To transport oxygen,' is incorrect because red blood cells are responsible for transporting oxygen. Choice C, 'To carry oxygen,' is also inaccurate for the same reason. Choice D, 'To produce antibodies,' while related to the immune system, is not the primary function of white blood cells, as their main role is to directly combat infections.

5. Which of the following substances can donate a hydroxide ion (OH-) in solution?

Correct answer: B

Rationale: The correct answer is B: Base. A base is a substance that can donate hydroxide ions (OH-) in solution. Bases increase the concentration of hydroxide ions by either accepting protons (H+) or donating hydroxide ions. Salts are ionic compounds made of cations and anions, which do not directly donate hydroxide ions. Neutral compounds do not significantly affect the concentration of hydroxide ions. Dehydrating agents are substances that remove water molecules from other compounds, unrelated to donating hydroxide ions.
