I would say the tone of this sentence is formal.
Is it a lion or a tiger ?
“any girl or boy who has not reached adulthood, for whom the street (in the broadest sense of the word, including unoccupied dwellings, wasteland, etc.) has become her or his habitual abode and/or sources of livelihood, and who is inadequately protected, supervised or directed by responsible adults”
Infinitives in the English language are relatives easy to spot. You just have to locate the word TO followed by a verb.
Here, the infinitive is to eat.
There is another TO in the sentence (to music), however, the word music is not a verb, which means that <em>to music </em>is not an infinitive.
The correct answer is "They recognize that she loves a human man".
Ariel and the others slyphs leave Belinda behind once they find out that she has feelings for a human male. Ariel is able to see Belinda's desire to be with this man by penetrating deep into her mind. T<u>hey are afraid that Belinda is going to lose her powers, since the slyphs will only protect her for as long as she rejects her involvement with the human race</u>, which she was no longer able to do because of her romantic feelings for a man.
Hope this is helpful to you!
