Answer Key

Limitations of the environment a solution works in

Section A: Quick Questions

A — An environmental limitation: poor or no internet connectivity

B — Let the app save data on the device and sync when a connection returns

A — Battery and power availability

B — Background noise limits the solution, so features like captions or noise reduction help

A — Offer a high-contrast display mode with large text

Section B: Match the Pairs

offlineMode = true → The app keeps working without internet by saving data on the device and syncing later

if battery < 20: dimScreen() → The system saves power by reducing screen brightness when the battery is low

Noisy places like a train station mean users cannot hear audio alerts, so the solution needs a visual backup → showBanner(alertText)

On a shared or public device the next person could see your data, so the solution must clear it when you finish → logout(); clearSession()

A map app that only works by loading every map from the internet, used by hikers in the bush → It ignores the environment: bush areas often have poor or no signal, so the app fails when hikers need it. It should allow maps to be downloaded for offline use.

A tablet menu with pale grey text on a white background, used by outdoor staff in bright sunlight → It ignores bright light: glare makes low-contrast text unreadable outdoors. It should use high-contrast colours and a bright screen setting.

Section C: Definitions

environmental limitation — A factor in the place a solution is used, such as poor internet, low battery, noise, bright light or a shared device, that restricts how well the solution works.

Section D: Fill in the Blanks

IF internet = "none" THEN
  SAVE data TO device
END IF

IF battery < 20 THEN
  SET brightness TO "low"
END IF

IF noiseLevel > 70 THEN
  SHOW captions
END IF

IF light = "bright" THEN
  SET theme TO "high contrast"
END IF

IF user = "finished" THEN
  DELETE savedPassword
END IF

Section E: Spot the Error

B — With no internet, the app cannot fetch live data. Line 2 should tell the user the app is in offline mode, for example SHOW 'Offline mode'.

A — Power saving should start when the battery is LOW. The condition should be battery < 20, not battery > 20.

D — In a noisy place a quiet beep cannot be heard. The solution should use a non-sound alert such as VIBRATE phone.

D — Bright light makes a dim screen hard to read. The brightness should be increased, not decreased.

C — On a shared device the next person could see the previous user's account. The user should be logged out with LOG_OUT user.
