Question 2
2.1 Nature and Origin of Science:
Natural Science involves finding out and making sense of the natural world. Natural Science
is stuck on the belief that nature is comprehensible, which means that it is rationally
ordered and can be known and understood. The subject combines direct, experimental
investigation of nature with reasons, inductive logical thinking in order to interpret, explain
and make theories about the patterns observed in nature.

part in eliminating many diseases, pests and famine. NS has some moral value.
