Which of the following can a variable in Scratch hold?

Question

BlackTom AI · Accepted Answer

Let's break down what a variable in Scratch can store by examining each option in turn.
Option a: 'Only numbers' suggests that Scratch variables are restricted to numeric values. In reality, Scratch variables can hold more than just numbers; they can store text as well, so this option is too limited.
Option b: 'Both numbers and letters' captures a broader and accurate view. Scratch variables can store numbers, but they can also store text strings (letters, words, and characters), since values are stored as strings or numbers depending on the context. This makes it the most correct choice among the options.
Option c: 'Only letters' would exclude numeric data, which is false because Scratch variables can hold numbers just as letters. Any claim restricting to letters misses the numeric capability.
Option d: 'Neither numbers nor letters' would imply variables hold something other than numbers or text, which is incorrect for Scratch, where the contents are typically numbers or strings.
Overall, assessing the capabilities of Scratch variables shows they are not limited to numbers or to letters alone; they can store both types of data, with numbers and strings being the common forms of values used in projects.
