Explanation:

1. Input Devices:

• A touchscreen and microphone are input devices. A touchscreen allows users to input commands by touching, and a microphone inputs audio. A speaker and monitor are output devices.

1. Processing and Output:

• In each option (A - D), there is a processing action (counting clicks, checking guesses, comparing scores) followed by an output (screen update, message, music play, score update).

1. Computer Storage:

• Computers can store apps (software), photos (images), music (audio), and location (data related to position).

1. Computing Limitations:

• Computing can help with counting, measuring, finding, and comparing (options A - C). But taking actions to reverse climate change (D) and passing laws (E) involve human decision - making and policy - making beyond just computing.

Answer:

1. A. Touchscreen, B. Microphone
2. E. All of the above
3. E. All of the above
4. D. Take actions to reverse climate change, E. Passing laws to reduce fossil fuels
