Overall, which phrase best describes the tone of this passage? ROMEO
O, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
As a rich jewel in an Ethiop's ear-
Beauty too rich for use, for Earth too dear.
So shows a snowy dove trooping with crows
As yonder lady o'er her fellows shows.
The measure done, I'll watch her place of stand
And, touching hers, make blessèd my rude hand.
Did my heart love till now? Forswear it, sight,
For I ne'er saw true beauty till this night.

Teach' here is a bit like 'teaching someone a lesson' or 'schooling' someone: it's got an air of competition to it. Romeo is saying that the (poor, dim) torches could learn a thing or two from Juliet about how to shine brightly. The rest of Romeo's speech is an elaboration of this idea.

Explanation:

recent brain research has shown some surprising benefits as a result of formal musical training. learning to play a musical instrument appears to develop parts of the brain that can even influence academic results. the studies indicate that the earlier a child begins training, the more benefits there are. one such study showed that children who began musical studies before the age of seven had a more developed brain in the region where language production and auditory processing take place. scientists believe there is mounting evidence to show that early musical training can improve brain function.

explanation:

the answer is "began" because it is a action that can be done
