This question is incomplete, here´s the complete question.
If you've ever tasted homemade jam, you know the
delicious rewards canning can bring. Although it is fun and
fulfilling, canning is not an easy task. First of all, you need
to grow or buy fresh fruit and wash it carefully. Then the
clean fruit has to be mashed, heated to a boil, and mixed
with sugar and pectin to get it to gel. Once the fruit is
ready, it must be poured carefully into clean, hot glass jars.
Next, add a lid and submerge the jars in a boiling water
bath for about 10 minutes. As they cool, the "pop" of the
lids tells you they have sealed.
What is the main idea of this passage?
A. If the lid doesn't "pop," the jar is not sealed properly.
B. The jars used for canning must be hot as well as clean.
C. In addition to fruit, you can also can many vegetables.
D. Canning is fun, but it takes a lot of work and knowledge.
