Answer:

a. Cats see low-frequency, low contrast objects better than humans.

Explanation:

Mr. Big is able to see something that Pamela does not see because cats have a wider field view of about 200 degrees while that of humans is about 180 degrees.

Cats eyes have 6-8 times more rod cells, which are more sensitive to low light, than that of humans. Their elliptical eye shape, large tapetum and cornea help to gather light for better vision at night.

Vitek1552 [10]

The available options are:

a) Push-up plus off a wall → shoulder IR/ER → seated DB press

b) Shoulder IR/ER → push-up plus → seated DB press

c) Shoulder IR/ER → seated DB press → push-up plus

d) High-rep bench press → shoulder IR/ER → abdominal crunch

Answer:

A. Push-up plus off a wall -> shoulder IR/ER -> seated DB press

Explanation:

A push-up plus off a wall is an example of a closed chain exercise as the arm is fixated to a stationary surface.

It also make your shoulder blades to move freely, making serratus anterior stronger, a vital muscle that keeps scapula stable and helps it rotate upward. This in turn reduces shoulder impingement when push-ups plus off a wall is done.

Shoulder IR/ER also helps to correct the imbalance in the rotator muscles of the shoulder.

Also, seated DB press strengthens all muscles of the shoulder in a functional way.
