Explanation:

Question 11

A conflict of interest in research occurs when personal/financial interests could bias results. Option a is about no funding, b about no interest, c about transparency—none define conflict of interest. Only d matches the definition.

Conceptual models simplify reality by focusing on specific aspects of a system. Physical models are tangible, computer models use software, mathematical models use equations—conceptual models are abstract and focus on key aspects, leading to oversimplification.

A hypothesis is a testable prediction about a phenomenon. It’s not a conclusion (a), doesn’t summarize research (c), and a theory describes patterns (d). So b is correct.

Answer:

d. When personal or financial interests could bias research results
