Answer:
phrase[2:5]
Explanation:
Given:
The above code segment
Required
Which instruction returns 'u a'
First, we need to get the index of u in the phrase:
u is at the third position but in programming, index starts at 0.
So, u is at index 2
Next, we need to get the index of a in the phrase:
a is at index 4
One of the ways to return a sub string from a string in python is ![string[start:stop+1]](https://tex.z-dn.net/?f=string%5Bstart%3Astop%2B1%5D)
Where:
----- index of u
----- index of a
phrase ---- The string variable
So, the instruction that returns 'u a' is: ![phrase[2:5]](https://tex.z-dn.net/?f=phrase%5B2%3A5%5D)
<em>Where 5 = 4 + 1</em>

Explanation:
The bit SYN is used in order to synchronize segment numbers in the sender and receiving processes in hosts that are trying to start a data transmitting session between them.
It is initiated by the sending end, that set this bit to " 1", in the TCP header, starting which is known as a "3-way handshake process".
The bit SYN is not used in order to close a connection, the FIN bit is used for this purpose.
If one process set the FIN bit to "1", this means that it has no more data to send.
