Transcript:

Bees are nectar experts. They are really good at assessing even really small differences in, like, sugar concentration of nectar. They also scope out the shape and size of flowers and their colour and scent. And now Leonard and her colleagues have discovered that bumblebees are pollen aficionados, too. They found that out by lacing batches of cherry pollen with either table sugar or bitter quinine. And to display the pollen to bees We got really into it we started 3D printing flowers in our lab. And for the anther the male flower part, which presents the pollen - pipe cleaners. So we bought out Michael's craft store supplies of these pipe cleaners and used them in our experiments. Turns out bees would return again and again to the same color flower that dispensed sweet pollen, and spend more time collecting there. But when confronted with the bitter pollen? They sought a different colored flower for their very next stop. All of which suggests that, in addition to savoring nectar, bees taste pollen too - and judge flowers by it. The results are in the journal Biology Letters.

* Click on the correct answer

Bees scope out the shape and size of flowers and their colour and scent. And return again and again to the same color flower that dispensed sweet pollen. Bumblebees prefer pollen with bitter quinine as compared to table sugar. They also spend more time collecting nectar from different colored flowers. Bees critically assess all aspects of flowers. Bumblebees are keenly able to scrutinise pollen too, which has been confirmed by experiments. Bees are really good at assessing even really small differences in sugar concentration of nectar. But they stay away from pipe cleaners, which are used in experiments.

Result:

A.I. Explanation:

Option 1: "Bees scope out the shape and size of flowers and their colour and scent. And return again and again to the same color flower that dispensed sweet pollen."
Explanation: This option is incorrect because it only partially summarizes the text. While it mentions bees assessing flower characteristics and returning to flowers with sweet pollen, it omits the critical point that bumblebees also assess pollen and that their preferences are influenced by the taste of the pollen. This option lacks the comprehensive view of the bees' abilities as described in the text.
Option 2: "Bumblebees prefer pollen with bitter quinine as compared to table sugar. They also spend more time collecting nectar from different colored flowers."
Explanation: This option is incorrect because it misrepresents the findings of the text. The text states that bumblebees prefer sweet pollen over bitter quinine, not the other way around. Additionally, it inaccurately suggests that the bees spend more time collecting nectar from different colored flowers, while the text emphasizes their preference for sweet pollen from specific colored flowers.
Option 3: "Bees critically assess all aspects of flowers. Bumblebees are keenly able to scrutinise pollen too, which has been confirmed by experiments."
Explanation: This option is correct as it encapsulates the main idea of the text. It highlights that bees assess various aspects of flowers, including shape, size, color, and scent, and emphasizes that bumblebees also evaluate pollen, which is supported by the experiments mentioned in the text. This comprehensive summary aligns well with the overall theme of the text.
Option 4: "Bees are really good at assessing even really small differences in sugar concentration of nectar. But they stay away from pipe cleaners, which are used in experiments."
Explanation: This option is incorrect because it focuses on a specific detail about bees assessing sugar concentration in nectar, which is only a part of the text. It also introduces the irrelevant point about pipe cleaners, which does not contribute to the main idea of the text. The option fails to capture the broader context of bees' assessment of both nectar and pollen.
