Final answer:
In Alice programming, a sequential block of instructions is executed using the 'Do in order' statement, which is missing from the provided options. The options listed serve other purposes, such as conditional execution and loops.
Step-by-step explanation:
In the Alice programming environment, to create a block of instructions that will execute in sequence, you use the Do in order statement. This is not one of the options provided in the question, so it seems there might be a misunderstanding or typo. The options given, such as the if statement, while statement, for statement, and do together statement serve different purposes. The if statement is used for conditional execution, the while and for statements are used for loops, and the do together statement is for executing multiple instructions simultaneously. For a sequential execution of a block of instructions in Alice, you would look for the Do in order or similar phrasing, rather than those provided in the options.
