Pick an answer to check it
wrongNot this one · the answer is DExplanation
A considerable share of the grains and fruit humans eat depends on bees pollinating flowers, showing that bees are very important to agricultural production, so D is correct. A: the passage says bees’ 「更大的贡献在于传播花粉」 (greater contribution lies in spreading pollen), not honey. B: it says bees 「在花朵之间飞来飞去」 (fly from flower to flower), carrying pollen to another flower; it does not say they stay on only one kind of flower. C is opposite to the statement that bee numbers in 「一些地区」 (some areas) have clearly declined.
