Find five examples of blake’s use of questions in the poems "the lamb" and "the tyger,” and compare their tone.

In the Lamb the entire first stanza consists of questions which only have one Dost thou, but it is applied to the other lines also. In the Tyger, the five questions can be What immortal hand or eye, Could frame thy fearful symmetry? 

In what distant deeps or skies. 
Burnt the fire of thine eyes? 
On what wings dare he aspire? 
What the hand, dare seize the fire? 

And what shoulder, & what art, 
Could twist the sinews of thy heart?

The tones are different insofar that the lamb has gentle questions and beautiful and timid descriptions, while the tyger questions are frightened and amazed that something so fierce exists. The main question in both is how the same god can make both something as gentle as a lamb and as fierce as a tiger.
