Neurofeedback involves trying to change brain wave activity.
<h3>Brain wave</h3>
The human brain is an intricate organ that baffles many scientists today. One design feature of the human brain is its ability to send signals in the form of brain waves when the mind is ar work or in a state of rest. These brain wave activity are braodly categorized into four types, namely;
- beta waves
- alpha waves
- theta waves
- delta waves
Neurofeedback thus occurs when an attempt is made to change from one of the above brain wave types to another.

A sauce should do all of the following except dominate all of the food that it accompanies.
<h3>What is a sauce?</h3>
This is the part of a meal that is usually added as a topping to that meal. The function of a sauce is to add richness to a meal that is served. Thr sauce is also known to add flavor to a meal. Example of a sauce is a tomato stew that is used to eat rice.

"Has" would make more sense. A tip would be to read the sentence with both words, one word at a time obviously (So Everyone HAS already voted in the election.) and just go with your gut on which one makes more sense, you can do it!
Odd. Hence +1
r

is even, and one of
p

. We may assume that =2
p
=

. Then we get 2=+1

q
