Correct
Solution (c)
The typical regions of monsoon forest are found in Myanmar, Thailand, and Cambodia.
Hence Statement 1 is correct.

Question 4 of 10
4. Question
Consider the following statements:
- Subtropical evergreen forest is generally found in regions of moist subtropical climate, where winters are mild and there is ample rainfall throughout the year.
- The subtropical broadleaf evergreen forest has fewer tree species than the low-latitude rainforests.
Which of the statements given above is/are NOT CORRECT?
Correct
Solution (d)
Subtropical evergreen forest is generally found in regions of moist subtropical climate, where winters are mild and there is ample rainfall throughout the year. This forest occurs in two forms: broadleaf and needleleaf
Hence Statement 1 is correct.
The subtropical broadleaf evergreen forest has fewer tree species than the low-latitude rainforests, which also are home to broadleaf evergreen types. Trees are not as tall here as in the low-latitude rainforests, and their leaves tend to be smaller and more leathery; thus, the leaf canopy is less dense.
Hence Statement 2 is correct.
