Answer:(c) abstract class A { abstract void unfinished(); }

I am almost positive the answer is B, Earth's crust. I know it cannot be A or C because isostasy has nothing to do with sea level or glaciers, and Earth's mantle is inside.
Answer:
I will code in JAVA.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
boolean tallEnough;
boolean oldEnough;
Scanner input = new Scanner(System.in);
tallEnough = input.nextBoolean();<em> //wait the input for tallEnough</em>
oldEnough = input.nextBoolean(); <em>//wait the input for OldEnough</em>
if(tallEnough && oldEnough){
System.out.print(true);
} else {
System.out.print(false);
}
}
}
Explanation:
First, to accept user inputs you have to import the class Scanner. Then declare both variables before allowing the user to set input values for both boolean variables.
In the if-else statement checks if both variables are true, then prints true. Another case prints always false.
Answer: Supermarket bar code scanners and Voice-activated telephone menus are not instances of artificial intelligence
Explanation:
(a)Supermarket bar code scanners are only able to read the code however they are not able to perform any kind of machine learning techniques to be able to learn a sequence from the codes. As machine learning is a important part of artificial intelligence (AI) so they are not instances of AI. Similarly for Voice-activated telephone menus they could only display and cannot perform any intelligent task.
Web search engines and Internet routing algorithms are very dynamic and intelligent in processing and retrieving information to the end user.
So they are instances of AI.
