Ishu was given an individual task of collecting weather reports for a week. Identify where Ishu went wrong from the assessment indicators given below:
A.She tabulates data from a website everyday.
B.She arrives at conclusion that rain may or may not take place in the coming week.
C.She concludes that decreased humidity increases the likelihood of rainfall.✓ Correct
D.She understands that range of maximum and minimum temperature varies everyday.
Explanation
Higher humidity, not lower humidity, increases the likelihood of rainfall, because rainfall requires sufficient moisture in the atmosphere. Decreased humidity actually reduces the likelihood of rain. Hence Ishu's conclusion in option 3 is scientifically incorrect. The other observations are valid weather-related conclusions.
