Discovering Main Ideas Worksheet
📖 Part 1: Reading Passage & Multiple Choice
Read the passage below and answer questions 1-4:
Honeybees are amazing insects that play a crucial role in our world. These busy workers visit flowers to collect nectar, which they turn into honey back at their hive. While gathering nectar, bees accidentally pick up pollen on their fuzzy bodies and carry it from flower to flower. This process, called pollination, helps plants reproduce and grow new seeds. Without bees pollinating plants, we wouldn't have many of the fruits and vegetables we eat every day, like apples, strawberries, and cucumbers. Farmers depend on bees to help their crops grow successfully.
