Question

Identify the correct pair.

• A. Bursting of a cracker - Fast change
• B. Decaying of vegetables - Fast change
• C. Germination of seed - Fast change
• D. Ripening of fruits - Fast change

Answer 1

The correct option is A Bursting of a cracker - Fast change

Changes that take place rapidly are called fast changes.
Bursting of cracker occurs rapidly in a very short span of time. Hence, it is a fast change.
Decaying of vegetables, germination of seed and ripening of fruits take little longer time and hence are slow changes.
