A.I. Explanation:

Option 1: "The receiving computer can determine whether or not the package is intact all by itself."

Explanation: The text states that the package includes information on how the receiving computer can verify that the package arrived intact. This implies that the receiving computer does not determine this on its own but relies on the information provided in the package.

Option 2: "In a packet-switching network, the data cannot be transmitted without being cut into packages."

Explanation: The text mentions that data is broken into packages for transmission, but it does not state that data cannot be transmitted in any other form. Therefore, this statement is too absolute and does not accurately reflect the text.

Option 3: "Apart from the data, a package also carries with it some other information."

Explanation: The text explicitly states that each package includes information such as the sender's address, receiver's address, and the package's place in the message. This confirms that the statement is true, as it accurately reflects the content of the text.

Option 4: "There are different routes for the transmission of data in a packet-switching network."

Explanation: The text indicates that packets can take the best available route, which may differ from the routes taken by other packets. This means the statement is true, as it aligns with the information provided in the text.
