Which among the following are the major reasons behind preferring Eucalyptus tree in the planned forestation process ?
1. Plantation grows very fast.
2. Plantation makes the soil more fertile.
3. Wood from Eucalyptus tree is easily converted into pulp for paper industry.

Select the correct answer using the code given below:

stats: 

0,26,33,5,26,8,20

keywords: 

{'eucalyptus tree': [0, 0, 1, 0], 'forestation process': [0, 0, 1, 0], 'plantation': [2, 0, 1, 0], 'wood': [2, 1, 4, 10], 'major reasons': [0, 0, 1, 0], 'paper industry': [0, 0, 0, 1], 'pulp': [2, 0, 3, 2]}

The correct answer is option-2, which includes reasons 1 and 3.

Reason 1 states that Eucalyptus trees have a fast growth rate, making them suitable for planned forestation. This means that they can be replenished quickly, providing a sustainable source of wood.

Reason 2, however, is not a valid reason for preferring Eucalyptus trees in planned forestation. Eucalyptus trees have been found to extract large amounts of water from the soil, making it less fertile for other plant species. This can lead to a decrease in biodiversity and negatively impact the surrounding ecosystem.

Reason 3 states that wood from Eucalyptus trees can be easily converted into pulp for the paper industry. This is a valid reason for preferring Eucalyptus trees as it can provide a valuable resource for paper production.

Therefore, option-2 is incorrect. The correct answer should be option-1, which includes reason 1 only.
