Boolean expressions control _________________Question 3Select one:a.recursionb.conditional executionc.alternative executiond.all of the above

To answer the question regarding what Boolean expressions control, we need to break down the options available:

1. Recursion: This typically involves a function calling itself and does not directly rely on Boolean expressions for its operation.

2. Conditional execution: Boolean expressions are essential to evaluating conditions that determine which path a program takes. This is a fundamental role of Boolean expressions in programming.

3. Alternative execution: Similarly, alternate execution paths in programming, such as if-else statements, depend on Boolean evaluations to decide which statement block to execute.

4. All of the above: This option suggests that Boolean expressions control recursion, conditional execution, and alternative execution altogether.

Conclusion

The best answer is b. conditional execution, as Boolean expressions directly govern the flow of execution based on conditions. However, d. all of the above could also be considered appropriate since Boolean expressions play roles in evaluating conditions that can influence recursion and alternative execution.

Thus, the answer is best determined as: d. all of the above.
