Step 3: Solve Question 31.
The passage describes Israt's family as having 10 members, including her paternal grandparents, an uncle, and an aunt, all living together. This structure, where multiple generations and extended relatives live under one roof, defines a joint family.

The question asks about Nim and Arhi based on the passage. The passage states they are the children of Israt's maternal uncle-aunt and study in a renowned school.
- i. একক পরিবারে বসবাস করে (live in a nuclear family) - Since they are the children of a maternal uncle-aunt, it implies they live with their parents, forming a nuclear family unit separate from Israt's joint family. This is likely correct.

All three statements are correct.
The correct option is (ঘ).
Step 8: Solve Question 36.
The question asks for the biggest obstacle to agricultural progress in Bangladesh.

Step 12: Solve Question 40.
The question asks for the time difference for 12°30' longitude in minutes.
We know that 1∘ of longitude corresponds to a time difference of 4 minutes.
First, convert 12∘30′ to degrees:
12∘30′=12+6030∘=12+0.5∘=12.5∘
Now, calculate the time difference:
Time difference=12.5∘×4 minutes/degree
Time difference=50 minutes
