Question 2

View answer

Two lunch boxes each stay shut in eight out of ten drops. One fails on the first two drops; the other fails on the last two. Which recording method would preserve this potentially useful difference?

A

Record only the final condition of the lunch box

B

Replace the lunch box after any failed drop and omit that result

C

Photograph the lunch box before testing instead of counting successful drops

D

Record the result of every drop, including which drop first caused the lid to open

B

False

Question 4

View answer

A student drafts the test plan while the prototype is still being developed. Beyond keeping a record of decisions, what practical advantage does this provide?

A

It guarantees that the finished prototype will pass every test.

B

It removes the need to collect evidence from the finished prototype.

C

It allows the student to identify the equipment and evidence needed while design changes are still possible.

D

It allows expected measurements to be entered as final results.

Question 5

View answer

An animation runs at 60 frames per second on the designer's laptop but at 20 on an older school computer used by the intended audience. Why does the second result matter?

A

Frame rate measures users' preferences rather than technical performance.

B

Older computers provide more accurate measurements than newer computers.

C

The animation's performance depends partly on the hardware used to run it.

D

A high frame rate on one computer proves that all animation controls work.
