Answer:
here are several methods of separating mixtures. The common ones are:
1. Winnowing
The wind is used to separate wharves (chaff), small sticks, and dry leaves, from grains or seeds by blowing the chaff away.
Chaff is usually lighter than the grains.2. Sieving
a sieve is used to separate mixtures of particles of different sizes. For example stones from flour.
The larger particles remain on the sieve while the finer ones pass through.
3. Picking
Here the large particles are separated from smaller ones by observing them and using the hands to remove the unwanted ones.
For example, stones are separated from rice or beans in this way.
4. Filtering
This method is used to separate a liquid from particles that cannot dissolve in it.
For example, separating sand from water using filter paper or piece of cloth.5. Decanting
This is when a liquid is separated from large particles of solids by pouring the liquid out gently.
For example, pouring off kerosene that has mixed with tiny ball bearings.

The question is incomplete as it does not have the option which are:
1. Halo
2. Leniency
3. Central tendency
4. Recency
Answer:
Leniency

A perceptual error is a phenomenon which occurs when the person holds some preconceived ideas about some other person on the basis of which the person is not able to make accurate perceptions about the person.
In the given question since the Dr. has not given less than B grade, this could be the result of the Halo type of perceptual error in which the person assumes that one parameter can be responsible for all other parameters and the person make incorrect errors like he could have considered attendance as a parameter ad on the basis of that he could have become more lenient towards the student with full attendance.
Thus, Leniency is the correct answer.
