Question 45

B) The number of baseball games in a season

Integer data types represent whole numbers without any decimal component. The number of baseball games in a season is a countable quantity, which fits the definition of an integer.

A) A single keystroke from a standard keyboard

This option refers to a character input rather than a numerical value. Keystrokes can represent letters, symbols, or commands, but they do not denote integer data.

B) The number of baseball games in a season

This option accurately represents integer data, as it is a whole number. The total number of games, typically 162 in Major League Baseball, is a discrete count, making it a perfect example of integer data.

C) An approximation of Pi as 3.14159

While this value is numerical, it is not an integer. The approximation of Pi includes decimal fractions, which disqualifies it from being categorized as integer data.

D) Whether a bank account does or does not have money in it

This option represents a binary state (yes or no) rather than a numerical value. While it can be related to integer data, it does not itself represent an integer.

Conclusion

The correct answer, B, is definitively right because it exemplifies a whole number that can be counted and categorized as integer data. All other options either do not represent numerical values or include decimal components, which excludes them from being classified as integers.
