Only the fittest survive______wild populations.

Detailed Explanation

Correct Answer

βœ“ Option (A) is correct. "Consequently" establishes a clear cause-and-effect relationship regarding survival in wild populations.

  • B: Inadvertently - Means unintentionally; lacks a connection to survival traits.
  • C: Although - Used for contrast; contradicts the context.
  • D: Since - Can imply cause but lacks the specific resulting nuance needed.

⚑ Grammatical Traps & Mnemonics

Be cautious with conjunctions. "Consequently" should follow statements explaining causation. Remember: "Resultant terms like 'consequently' address outcomes, while 'although' points out contradictions."
