The hypothesis that one specific gene is responsible for a complex human behavior is ______, as it disregards the multifaceted interplay of genetic, environmental, and developmental factors. A comprehensive understanding would require the examination of a network of genes interacting with various external influences.2Mark for ReviewABCWhich choice completes the text with the most logical and precise word or phrase?AirrefutableBreductiveCgroundbreakingDcorroborated

To answer the question step by step:

1. Understand the context: The sentence discusses the complexity of human behavior and the factors influencing it, suggesting that attributing it to a single gene is an oversimplification.

2. Analyze the choices:

   • A. irrefutable: Means impossible to deny or disprove. This does not fit because the sentence implies that the hypothesis is overly simplistic, not undeniable.
   • B. reductive: Means overly simplified, especially in a way that disregards complexity. This fits well because the sentence suggests that attributing complex behavior to one gene ignores other factors.
   • C. groundbreaking: Means innovative or pioneering. This does not fit because the sentence criticizes the hypothesis rather than praising it.
   • D. corroborated: Means supported with evidence. This does not fit because the sentence implies that the hypothesis is not well-supported.

3. Select the most logical and precise word: Based on the analysis, the word that best completes the sentence is "reductive."

So, the completed sentence is: "The hypothesis that one specific gene is responsible for a complex human behavior is reductive, as it disregards the multifaceted interplay of genetic, environmental, and developmental factors. A comprehensive understanding would require the examination of a network of genes interacting with various external influences."
