Assertion: The understanding of concepts of friction and heat helped the humans to discover fire. Similarly, understanding of the secrets of DNA and genetics enabled us to conquer many diseases.
Reasoning: Human beings were able to develop technology after they developed better understanding of natural laws.
Answer & explanation
Correct answer: option 1
The correct answer is Option 1: Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.
Here's why:
-
Assertion (A): The statement accurately reflects how understanding friction and heat (leading to fire) and DNA/genetics (leading to disease control) are pivotal advancements. These discoveries are based on understanding natural principles.
-
Reasoning (R): This is a true statement. Technological development is fundamentally linked to our understanding of natural laws. We can't build complex tools or manipulate natural processes without grasping the underlying scientific principles.
-
Connection: The reasoning directly explains the assertion. The examples in the assertion (fire, disease control) are direct results of the process described in the reasoning (understanding natural laws leading to technology). Therefore, R is the correct explanation of A.
