Depending on the prompt I`d say formal tone. As if you were going into an interview
Answer:
The U.S. Army wants to locate bears that have dens on their training grounds. It hired John, a biologist in Alaska, to find out where the bears hibernate.
Explanation:
A summary is a shortened version of a piece of writing, such as a paragraph, excerpt, chapter, or an entire book. It should include the main ideas of the text and only the most important details.
The option that fulfills these criteria is the first one. It summarizes what the text is about - about how the U.S. Army wants to locate bears that have dens on their training ground and how it hired a biologist named John to find them. The main point is covered and there are no unnecessary details.
The second option is the second best. However, it doesn't include some important details - the location and the name of the biologist.
The third and fourth options are incorrect because they include too much detail.
The human eye is a wonderful instrument, relying on refraction and lenses to form images. There are many similarities between the human eye and a camera, including:
a diaphragm to control the amount of light that gets through to the lens. This is the shutter in a camera, and the pupil, at the center of the iris, in the human eye.
a lens to focus the light and create an image. The image is real and inverted.
a method of sensing the image. In a camera, film is used to record the image; in the eye, the image is focused on the retina, and a system of rods and cones is the front end of an image-processing system that converts the image to electrical impulses and sends the information along the optic nerve to the brain.
The way the eye focuses light is interesting, because most of the refraction that takes place is not done by the lens itself, but by the aqueous humor, a liquid on top of the lens. Light is refracted when it comes into the eye by this liquid, refracted a little more by the lens, and then a bit more by the vitreous humor, the jelly-like substance that fills the space between the lens and the retina.
The lens is critical in forming a sharp image, however; this is one of the most amazing features of the human eye, that it can adjust so quickly when focusing objects at different distances.
