Honeybees have no photoreceptor for red light and cannot distinguish a red blossom from the dark green leaves around it. ______, flowers that depend on bees for pollination are almost never pure red; they tend toward blue, violet, and yellow.
Which choice completes the text with the most logical transition?
- A) Similarly,
- B) Accordingly, ✓
- C) For example,
- D) Nonetheless,
Why: The passage explains that honeybees "cannot distinguish a red blossom from the dark green leaves around it," and then draws the consequence: flowers relying on bees "are almost never pure red." Because the flower color is presented as an effect of the bees' vision limits, the blank needs a cause-and-effect transition, which "Accordingly," supplies. "Similarly," wrongly implies the flower-color fact merely resembles the bee-vision fact rather than following from it. "For example," wrongly treats flower coloration as an instance of bee vision, but the two are different categories, a color pattern and a visual limitation, not a case-and-category relationship. "Nonetheless," wrongly signals concession or contrast, when the flower coloration is a direct, expected result of the bees' inability to see red rather than something that pushes against it.
