Question

The two boys Nicola and Jacopo, though very young in age, were very mature in their deeds. Comment.

Answer 1

Ya it's true that Nicola n Jacopo were very young in age but so mature in their deeds as they have done many jobs like hawked newspaper, selling strawberries and work as a guide. They were enough mature to do these works and how to behave with a stranger. They were doing all these works only to pay their sister's hospital charges like a mature and capable person.
Hope it helps u dear

Answer 2

Here's an example..
The boyq
s had self-confidence, determination and their mature, healthy and selfless attitude towards life. Without indulging in any self pity or arousing other's sympathy, they eagerly undertake any piece of work that would be a means of earning for them as they needed money to pay for the treatment of their tuberculosis-affected sister.

They believed in fighting their own battles in life. They din't like to look for shoulders to leave upon.
