A) it should restate the question
This is because a sample is supposed to ideally represent the whole population from which it was taken. Taking samples from different location within the population ensures that they are no bias in the sample. Each part of the population should be well represented in the sample so that the conclusions drawn from the sample represent the properties of the whole population.

Answer:Inducible;inducer
Explanation:
Induction is the phenomenon of increased synthesis of protein or and enzyme in response to certain signal. Such enzymes are called inducible and the signals are called inducer. Induction is turning ''on''the switch of a gene.
When M is present in the medium, M binds the repressor protein. The repressor-M complex is inactive which does not bind to the operator region of LM. Now RNAP can transcribe the structural genes of LM.
M switches the gene ''on''. Hence M is an inducer of LM. LM is an inducible operon
