Based on the speakers words and emotions in the pooms "Escape" and "To Live," the theme that there are many parts to a

person's identity is expressed

in neither poem

in both poems

only in "Escape"

only in "To Live"

C). In both poems.

Explanation:

As per the question, both the poems 'Escape' and 'To Live' on the basis of the words as well as emotions display the theme of 'expression of varied parts of a person's identity'.

In 'Escape' the speaker first says 'I wonder' while another moment, he says 'but, I don't know' and after that, he says 'I must take this test just like everyone' which implies the confusion or struggle to identify one's own place or purpose in this world due to the presence of various layers in our identity while 'To Live' also expresses the similar idea and confusion when it says 'learning without knowing' and 'how to know myself to be myself', 'my mind on text', 'my pen on page', etc. Thus, these instances portray the uncertainty that the speakers possess regarding their own identity as they are surrounded by the multiple dimensions of their identity. Therefore, option C is the correct answer.
