Writing Pattern :
Aurochs, large wild European cattle , which died out
in 1627, are worth restoring. Here are the reasons.
Aurochs have two long horns and thick hair. Their
horns can be used for decoration, which can make
homes beautiful. Besides, their hair is so long that it
can be used to make clothes. The most important
thing is that they can be raised in the galssland
eaily to help herdsmen make money.
So I think the aurochs are the best choice to bring
back to life for decoration, clothes and wealth.
