Answer Key
Possible future impacts of a solution
Section A: Quick Questions
Q1
B — Student photos could be leaked later if the server is hacked
Q2
A — It is an effect a solution could have later on people, the environment or the economy
Q3
B — Some cashier jobs may be lost over time
Q4
A — Lots of old tablets could become e-waste and use up resources
Q5
A — Fewer people may drive, so air pollution could drop over the years
Section B: Match the Pairs
Q1
future impact → An effect a solution could have later on people, the environment or the economy
Q2
long-term impact → An effect that shows up years after a solution is first used, such as e-waste from old devices
Q3
A future impact on privacy and security: an app stores personal data that could be leaked later → impact = 'data leak risk'
Q4
A future sustainability impact: a system uses lots of energy and creates e-waste → impact = 'high energy use'
Q5
impact = 'It works today, so there are no future impacts' → This only checks the present. A solution that works now can still cause effects later, such as job changes or more energy use.
Q6
impact = 'Only the people who use it are affected' → This ignores other people and the environment. A solution can affect non-users, the economy (like jobs) and the environment.

Q1
A — Text must be written inside quotation marks. It should be impact ← "energy use".
Q2
A — A FOR EACH loop needs the word IN between the item and the list. It should be FOR EACH impact IN impacts DO.
Q3
B — Jobs gained is stored as text, so line 3 can't subtract it. It should be a number: jobsGained ← 5.
Q4
C — An IF statement needs THEN at the end of the condition. It should be IF isPrivate = TRUE THEN.
Q5
C — The warning should show when battery life is below the target, meaning the solution uses too much energy. It should use < not >.
