Sex is defined as our assigned social roles

Correct Answer: B

Rationale: Step 1: Sex refers to biological characteristics such as chromosomes, hormones, and reproductive anatomy. Step 2: Assigned social roles are based on gender stereotypes and expectations. Step 3: Sex and gender are distinct concepts. Step 4: Therefore, sex is not defined by assigned social roles. Summary: Choice B is correct because sex is based on biological factors, not social roles. Choices A, C, and D are incorrect as they do not align with the accurate definition of sex.

Correct Answer: A

Rationale: The correct answer is A: Safety, affordability, and adequacy. Core housing need includes these factors as defined by the Canadian Mortgage and Housing Corporation. Safety ensures the dwelling is structurally sound, affordable means it doesn't exceed 30% of household income, and adequacy pertains to enough bedrooms for the household size. Option B focuses on adequacy, suitability, and location, lacking affordability. Option C includes affordability but misses out on safety. Option D mentions location and walkability, not covering affordability or adequacy.

Correct Answer: A

Rationale: The correct answer is A because melting glaciers contribute to rising sea levels due to increased water volume, and increased temperatures are a result of global warming caused by climate change. Melting glaciers also lead to the release of stored greenhouse gases, further exacerbating temperature rise. Choices B, C, and D are incorrect because lower sea levels and decreased temperatures are not consistent with the impacts of climate change, which is primarily characterized by rising sea levels and increased temperatures due to human activities.

Correct Answer: B

Rationale: The correct answer is B because microplastics are indeed tiny plastic particles with a diameter less than 3mm. This is a universally accepted definition of microplastics by researchers and environmental organizations. Choice A is incorrect as the health risks of microplastics are still being studied and not fully understood. Choice C is an exaggerated figure as the exact amount of microplastics in the oceans is difficult to determine. Choice D is incorrect because microplastics have been found in various food sources, including seafood, indicating that they do end up on our plates.

Correct Answer: D

Rationale: The correct answer is D: Depoliticizing health issues. Positivism in health sciences emphasizes the use of objective, measurable data and scientific methods to understand health phenomena. By depoliticizing health issues, positivism aims to focus on empirical evidence and logical reasoning rather than subjective opinions or political agendas. This approach helps ensure that health research and interventions are based on reliable data and scientific principles rather than biases or ideologies. A: Reliance on qualitative approaches is incorrect because positivism typically emphasizes quantitative methods and data analysis. B: Fixation on population health approaches is incorrect as positivism in health sciences focuses on individual-level factors as well as population-level trends. C: Committing to subjectivity is incorrect as positivism seeks to minimize subjective interpretations and biases in health research and practice.
