Explanation
PASSAGE
The biologist noted that while the species appears uniform to the naked eye, genetic analysis reveals a high degree of ______, indicating significant variation within the population.
Which choice completes the text with the most logical and precise word or phrase?
Detailed Answer Explanation
This question asks for the meaning of a word as used in this specific context. The text contrasts 'uniform' appearance with 'significant variation'. 'Heterogeneity' refers to the quality or state of being diverse in character or content. Words can have multiple meanings, and context determines which meaning applies. Read the surrounding sentences carefully. Substitute each answer choice to see which maintains the intended meaning and fits the context. Many vocabulary words have multiple dictionary definitions, but only one fits the context. Use the surrounding sentences as clues. Try substituting each answer choice to see which one preserves the author's intended meaning without changing the sentence's message.
Key Evidence:
• "genetic analysis reveals"
• "significant variation"
Why others are wrong: D (Homogeneity means being all the same.), B (Consistency implies uniformity.), A (Stagnation means lack of activity or growth.).
