Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.

Answer:
public class Main
{
public static void main(String[] args) {
int carYear = 1995;
if(carYear < 1967)
System.out.println("Probably has few safety features.");
if(carYear > 1971)
System.out.println("Probably has head rests.");
if(carYear > 1992)
System.out.println("Probably has anti-lock brakes.");
if(carYear > 2002)
System.out.println("Probably has tire-pressure monitor.");
}
}
Explanation:
The code is in Java.
Initialize the carYear
Use if statements to handle year before 1967, after 1971, after 1992 and after 2002.
Print the required message for each if statement
