Below are sample questions representative of the exercises included on this worksheet and related 4.25 Use Patterns to Transfer Information skill assessments:

Problem 1Difficulty: Mastery

Students want a noisy-room signal to be clear. Which plan would reduce confusion?

AChange the pattern every time

BMake the signal faster and skip pauses

CUse a pattern that no one practiced

DRepeat the pattern and agree on a pause between messages

Solution & Explanation:Repeating a clear pattern and using agreed pauses helps receivers notice and check the message without advanced probability ideas.

Problem 2Difficulty: Mastery

Which method is more reliable for an exact 6-symbol command?

AUse light because intermittent bangs can corrupt sound timing, while a dark background makes aimed light pulses high-contrast.

BUse light but widen the beam dramatically; wider beam reduces intensity and can reduce contrast.

CUse sound because it does not require aiming, even though bangs can mask symbols.

DUse sound and increase speed; speed doesn't avoid bangs.

Solution & Explanation:Burst noise can erase or add sound symbols. With a dark background, light pulses can be clearly detected if aimed, making the light channel more reliable here.

Problem 3Difficulty: Mastery

Which encoding reduces errors from brief blocks?,A. Use the 1-second slot method because brief blocks are less likely to hide the entire symbol compared with very short flashes. | B. Use very short flashes because they are easier to see in snow. | C. Use dimmer flashes; dimmer increases missed detections. | D. Either; brief blocks affect long and short symbols equally.,A. Use the 1-second slot method because brief blocks are less likely to hide the entire symbol compared with very short flashes.,Longer symbol windows provide time redundancy. A brief block can erase a short flash completely

Solution & Explanation:or code idea clearly and keep the image answer-neutral. Use this question context: Scenario: At night in falling snow
