The common domain for the variables is; It is true on every set with no more than 22 members and false on other sets.
<h3>What is the domain of the variables?</h3>
We are given the statement;
∀x∀y((x ≠ y) → ∀z((z = x) ∨ (z = y)))
Since x and y are different objects in the domain, then we can say that anything in the domain is equal to x or to y.
Now, If the domain M has two elements, it means that the given sentence will obviously hold. Also, a one-element domain will work since there wouldn't be a pair x, y such that x ≠ y.
We can conclude that the common domain for the variables is; It is true on every set with no more than 22 members and false on other sets.
An example is that it is true on {a,b} and false on R

That's correct
Gamma rays are the strongest rays we have because it has a high frequency. Radio waves are not dangerous like gamma because radio waves have low frequency and the waves are long.
Conflicts can be healthy because it enriches our thinking and maintains a relationship with others
The two true statements about redox reactions are:
C. One type of atom is oxidized and another is reduced.
D. Electrons are transferred from one atom to another.
<h3>What is a redox reaction?</h3>
A redox reaction is also known as an oxidation-reduction reaction and it can be defined as a type of chemical reaction in which the oxidation number of an atom of participating chemical species are changed.
This ultimately implies that, the two true statements about redox reactions include the following:
- One type of atom is oxidized while the other is reduced.
- Electrons are transferred from one atom of participating chemical species to another.
