The following question, consist of two words each that have a certain relationship to each other, followed by four lettered pairs of words. Select the lettered pair that has the same relationship as the original pair of words: Gland : Enzyme

The correct answer is: A. Muscle : Spasm

A gland is an organ that produces a substance that is released into the bloodstream or onto a surface of the body.

Enzymes are proteins that help to speed up chemical reactions in the body. A muscle is a tissue that contracts and relaxes to produce movement. A spasm is a sudden, involuntary contraction of a muscle or group of muscles.

In the same way that a gland produces an enzyme, a muscle

produces a spasm. A spasm is a type of involuntary muscle contraction that can be caused by a variety of factors, including injury, stress, or fatigue. Spasms can be painful and can limit movement.

The other options do not have the same relationship as the original pair of words.

• A generator is a device that converts mechanical energy into electrical energy. A current is a flow of electricity.
• An organ is a part of the body that performs a specific function. A kidney is an organ that filters waste products from the blood.
• The brain is the organ that controls the body’s functions. The cortex is the outer layer of the brain.
