Before tryouts began, the boys seemed puzzled. Where, they wondered, was the coach? Luma was right in front of them, but a woman soccer coach was a strange sight to young Africans, and to young Muslim boys from Afghanistan and Iraq. –Outcasts United,

Whose thoughts and feelings are revealed in the first two sentences?

What conclusion can be drawn based on the thoughts and feelings that are revealed?

The young boys' thoughts and feelings are revealed in the first two sentences.

We can conclude that through their reaction to seeing the woman coach, their society discriminates against the women and make them inferior to the men.

Explanation:

Outcasts United by Warren St. John tells the story of how a soccer team emerged from the refugees in the Georgian town of Clarkson despite their own misfortunes and even enmity among themselves. The effort of the coach Luma, who was also a female, and the common perception of not only the Americans but even the refugee families she's helping all acts as obstacles for the success.

From the given excerpt, the first two sentences reveal the thoughts and feelings of the young soccer enthusiasts who all came from different backgrounds and nationalities.

These thoughts on realizing that their coach is a female is rather shocking for them. Coming from backgrounds and nations (especially Muslim countries) that seems to be prejudiced against the female sex, the young boys find it hard to accept and believe that they will be taught soccer or even play under a women coach. This shows that society prioritizes men over women, thus making them inferior to the men.  

the central idea is basically saying that juveniles that have committed a crime will not have the same consequences as the   adults that have. they will have a softer punishment than what the adults have that is harsh in some ways.
