Difficulty: HardDeciphering Meaning via Structural Clues and Contrast/Continuation Signals

Read the following passage from an essay on the history of science:

"In late nineteenth-century evolutionary biology, many researchers refused to endorse Lamarckian mechanisms of inheritance outright; nevertheless, they continued to entertain such hypotheses whenever Mendelian models failed to account for rapid phenotypic adaptation under severe environmental stress. Far from signaling a permanent return to vitalist doctrines, this willingness to give serious consideration to soft inheritance was strictly provisional, serving merely as an empirical placeholder until sub-cellular processes could be fully elucidated."

In the context in which it appears, which of the following best captures the meaning of the word "entertain"?

  1. A
    amuse or provide diversion for
  2. give serious consideration toAnswer
  3. C
    harbor secret or illicit beliefs
  4. D
    definitively prove or validate
  5. E
    host or receive as guests

Answer

In the passage, "entertain" most nearly means to give serious consideration to.
The correct answer is 'give serious consideration to'. The passage sets up a contrast using 'nevertheless' after stating that scientists 'refused to endorse' the hypotheses outright, indicating that they were still open to contemplating them. Furthermore, the very next sentence directly restates this action as 'this willingness to give serious consideration', providing a structural definition clue.

Step-by-Step Solution

1
Analyze the structural signals and sentence context surrounding the target word.
The clause opens with a concession: researchers 'refused to endorse Lamarckian mechanisms... outright', followed by the contrast signal 'nevertheless, they continued to entertain such hypotheses'.
Contrast signals indicate a shift from total rejection ('refused to endorse') to a degree of open-minded evaluation ('entertain').
2
Identify structural elaboration clues in the subsequent sentence.
The following sentence rephrases the action as 'this willingness to give serious consideration to soft inheritance'.
Authors frequently clarify polysemous terms by elaborating on or restating them in adjacent sentences.
3
Match the synthesized contextual definition against the available options.
The phrase 'give serious consideration to' aligns precisely with both the contrast clue and the explicit restatement clue.
Selecting the meaning derived from contextual structural signals ensures accuracy over primary dictionary definitions.
