1. What is the recommended default for running a known executable with arguments?

   An argument sequence keeps each argument separate, and the default shell=False avoids shell parsing.
2. What does capture_output=True provide?

   capture_output=True captures stdout and stderr; check=True separately determines whether a nonzero return code raises.
3. When check=True and a child exits with status 5, what happens?

   A completed child with nonzero return code causes CalledProcessError when check=True.
4. Which exception indicates the configured run() time limit expired?

   TimeoutExpired reports that the child did not finish within the requested timeout.
5. Which option sends a string to a child's standard input when text=True is used?

   The input parameter supplies child standard input; text=True allows the input and captured streams to be strings.
6. Why should untrusted input not be interpolated into a string run with shell=True?

   The shell interprets metacharacters, which can turn crafted input into unintended commands. Prefer a sequence with shell=False.
