MYP Design Topic Evaluating a Solution Against the…

Question 1

Complete the statement: A product is intended to last two years, but the student has observed only four weeks of normal use and has no other durability evidence. The evaluation should describe this as __________.

A

proof that the two-year lifespan requirement is met

B

proof that the product will fail before two years

C

evidence limited to the four weeks observed

D

a reason to omit the lifespan requirement from the evaluation

Question 2

A printed fabric bag must retain its design after five machine washes. The student tests it by rinsing it by hand five times in cold water. What is the main limitation when evaluating this specification point?

A

The test does not establish whether the print survives machine washing.

B

The requirement is met because cold water is used in washing machines.

C

The test establishes that the print survives any type of washing.

D

The requirement should be judged using the appearance before washing.

A student is separating evaluation statements from proposed improvements in an accessible control-panel project. Which sentence belongs in the evaluation of the finished solution?

A

Another activation-force test should be scheduled after the screen is replaced.

B

The next version should use a more sensitive screen.

C

A larger button could make the interface easier to operate.

D

The screen required 12 N to activate in Test 4, exceeding the specified maximum of 5 N.

Question 4

A repairable torch must allow its battery to be replaced in under two minutes. The test times removal of the old battery at 45 seconds but stops before insertion, reassembly and checking operation. Which evaluation is supported?

A

Double the removal time and use that estimate as the final result.

B

Mark the requirement as met because removal is usually the hardest step.

C

Mark the requirement as not met because the remaining steps must take longer than two minutes.

D

Report that removal met the time target, but the complete battery-replacement task remains unverified.

Question 5

View answer

A specification requires a box lid to stay shut in at least 9 of 10 drops from 75 cm. The final box succeeds in 8 of 10 drops. Which judgement is best supported?

A

Partly met, because the lid stayed shut in some drops but fell below the required threshold.

B

Not tested, because the test included unsuccessful drops.

C

Met, because the lid stayed shut more often than it opened.

D

Met, because one more successful drop would have reached the threshold.
