2.
According to Emily, what can affect the measurement results?
The brand of the sensor
The color of the sample
The number of technicians present
Noise in the environment
Explanation:
Emily says, ‘Noise can affect the results.’
3.
What does Emily say about measuring very small changes?

It is easy and very accurate
It is impossible in any environment
Explanation:
Emily says, ‘Small changes are hard to detect. The sensitivity is limited.’
4.
What can be inferred about the measurement technique?
It works best when samples are very complex
It cannot be improved in any way
It always gives fast results regardless of the environment
It is most reliable when conditions are simple and stable
Explanation:
Emily says the method is affected by noise and temperature, can be slow, and works best with simple and uniform samples, which suggests it is most reliable under simple and stable conditions.
5.
What does Emily suggest to reduce the method’s limitations?
Heating the samples before measuring
Avoiding all materials completely
Using better sensors and noise filters
Changing the sample color
Explanation:
Emily says, ‘We can try better sensors and noise filters.’
