The variable age is to be used to represent a person’s age, in years. Which of the following is the most appropriate data type for age?

• Boolean

• number

• string

• list

• The value of first is true, and the value of second is true.

• The value of first is true, and the value of second is false.

• The value of first is false, and the value of second is true.

• The value of first is false, and the value of second is false.

• Step 1: Add num1 and num2 and store the result in the variable sum.

  Step 2: Take the absolute value of sum and display the result.

• Step 1: Subtract num1 from num2 and store the result in the variable diff.

  Step 2: Take the absolute value of diff and display the result.

• Step 1: Take the absolute value of num1 and store it in the variable absNum1.

  Step 2: Take the absolute value of num2 and store it in the variable absNum2.

  Step 3: Add absNum1 and absNum2 and display the result.

• Step 1: Take the absolute value of num1 and store it in the variable absNum1.

  Step 2: Take the absolute value of num2 and store it in the variable absNum2.

  Step 3: Subtract absNum1 from absNum2 and display the result.

• val1 = true, val2 = true

• val1 = true, val2 = false

• val1 = false, val2 = true

• val1 = false, val2 = false

• The output will be true no matter what the value of input B is.

• The output will be false no matter what the value of input B is.

• The output will be true if input B is true; otherwise it will be false.

• The output will be false if input B is true; otherwise it will be true.

A certain game keeps track of the maximum and minimum scores obtained so far. If num represents the most recent score obtained, which of the following algorithms correctly updates the values of the maximum and the minimum?

• If num is greater than the minimum, set the minimum equal to num. Otherwise, if num is greater than the maximum, set the maximum equal to num.

• If num is less than the minimum, set the minimum equal to num. Otherwise, if num is greater than the maximum, set the maximum equal to num.

• If num is less than the minimum, set the minimum equal to num. Otherwise, if num is less than the maximum, set the maximum equal to num.

• If num is greater than the minimum, set the minimum equal to num. Otherwise, if num is less than the maximum, set the maximum equal to num.
