The task is to identify the sentence that doesn't fit within a coherent paragraph about gender and its perception as either a natural or social construct. To solve this, let's analyze the sentences:
- No known real researcher of human behaviour would say that gender is all nature or all nurture.
- The evidence for a biological basis for gender certainly doesn’t mean we should be complacent in the face of sexism.
- Many people are uncomfortable with the idea that gender is not purely a social construct.
- Despite this empirical truth, researchers who study the biological basis of gender often face political pushback.
- There’s a political preference for gender to be only a reflection of social factors and so entirely malleable.
Contextually, sentences 1, 3, 4, and 5 discuss the nature vs. nurture debate regarding gender and the political implications of perceiving gender as a social construct. Sentence 2, while relevant in its own right, diverts from the primary discussion about perception and backlash faced by researchers. Thus, the odd sentence is:
Sentence 2: The evidence for a biological basis for gender certainly doesn’t mean we should be complacent in the face of sexism.
