Answer: A
Character string
The appropriate data type for holding the brand name of a product in an inventory is a character string. This data type allows for the storage of textual information, which is essential for representing names and descriptions.
A) Character string
Character strings are specifically designed to hold sequences of characters, making them ideal for storing names such as brand names. Since a brand name consists of letters, numbers, and possibly other characters, the character string data type can accommodate this requirement effectively.
B) Boolean
Boolean data types can only store two values: true or false. They are not suitable for representing textual information such as brand names, which require more complex data handling than just binary values.
C) Floating point
Floating point data types are used for representing real numbers, particularly those that require decimal points. Since brand names are composed of characters rather than numerical values, floating points are not applicable in this context.
D) Character
While a character data type can hold a single character, it is insufficient for storing an entire brand name, which typically consists of multiple characters. Therefore, while it is relevant, it does not meet the requirement for a variable that needs to hold a brand name.
Conclusion
The character string data type is definitively the correct choice for storing brand names due to its ability to handle multiple characters in a sequence. All other options fail to meet the requirements: Boolean is limited to true/false values, floating point is for numbers, and character only stores single characters, making them inadequate for the task at hand.
Answer: B
Whether a number is positive or not
Boolean data represents truth values, typically expressed as true or false. An example of Boolean data is determining whether a number is positive, as it can only be true or false based on its value.
A) The price of gas in dollars and cents
This option is incorrect because the price of gas is a numerical value that can take on a range of values and is not limited to just two states. It does not fit the definition of Boolean data, which is confined to binary outcomes.
B) Whether a number is positive or not
This option is correct as it presents a clear binary choice: a number can either be positive (true) or not positive (false). This aligns perfectly with the characteristics of Boolean data.
C) The last name of a newly hired employee
This option is incorrect because a last name is a categorical variable that can take on numerous values and does not represent a binary state. It does not qualify as Boolean data since it is not limited to two possible answers.
D) The first letter of a person's last name
This option is incorrect as well, as the first letter of a last name can be any letter from the alphabet, making it a categorical variable rather than a Boolean one. It does not fit the definition of having only two states.
Conclusion
The correct answer, whether a number is positive or not, exemplifies Boolean data by presenting a binary choice between two states. All other options fail to meet the criteria for Boolean data due to their categorical or numerical nature, which does not provide a true or false outcome. Thus, option B is the only suitable example of Boolean data.
