Answer:
The oblique illumination is
used by the microscopists to resolve N. Spencrii in the Dark Field Condensers.
Explanation:
It was found that the use of oblique light was required to resolve the striae. Oblique illumination was the first step toward dark field microscopy. In dark field, light
seems to radiate from the specimen while all the rest of the field is black. Resolution is as good as that in bright field while contrast is enhanced.
In dark field microscopy, no
direct light from the condenser enters the objective lens. Only light
that is reflected, refracted or diffracted by the specimen enters the objective. The dark field condenser produces a circle of light. The
light is at an extremely oblique angle to the surface of the slide. This
oblique light comes to a focus on the specimen. It then diverges so
strongly that no direct light enters the objective. This type
of illumination is a hollow cone of light.

Explanation:
The correct answer to this open question is the following.
Compare rules you may follow at home, at school, or at work. As you cross internal boundaries each day, why would each of these places have separate sets of rules?
At home, absolute I have to follow family rules. They are basic but non-negotiable. More than rules, these are principles that are base on love and commitment.
But when I am at school, yes, there is a set of rules on how to behave in class and on the premises, and how to correctly relate to each other, It is a challenge. It is my personality, behavior, and customs versus other students' and teachers' ideas. It is not an easy thing to do.
The workplace is something similar but with professional connotations. As pro people say, it is a job and you have to behave like one because the consequences are tough.
So it is true that we have to obey a different set of rules, according to the place we are.
Agriculture, to infrastructure activities, to tourist attractions
