Answer 1

Answer: (B), (C)

The correct options are
B Making of sweater from wool
C Making of paper from wood

Changes that do not occur naturally but occur due to human intervention are known as man-made changes.

Manufacturing of sweater and paper from wool and wood respectively needs human intervention. Thus, these changes are man-made.

Human beings have no involvement in the seasonal changes and falling of leaves. Thus, these changes are natural.
