Answer:
phrase[2:5]
Step-by-step explanation:
Given:
The code fragment
Required
The missing line of code
From the question, we understand that the missing line is to return 'u a'
The first character is u.
So, we need to get its index in the phrase variable
u is at index 2
The next character after u is a blank, and it is at index 3
The next after the blank is character a and a is at index 4
To return a sub string from a string in python, the following syntax can be used.
string[start:stop+1]
From the analysis above;
start = 2 i.e index of u
stop = 4 i.e index of a
and the string variable is phrase
So, the instruction that returns 'u a' is:
phrase[2:4+1] or phrase[2:5]
