c.

d.

Two blood brothers

Step-by-step explanation:

What we will do is go through each statement and we will give it a true domain and a false domain:

a.) Everyone is studying discrete mathematics.

Domain true = {Everyone in the Discrete Math class}

True because they belong to the math group

Domain false = {Everyone in the city}

False because in the city not everyone gives this type of mathematics.

b.) Everyone is older than 21 years.

Domain true = {People who receive their pension contribution}

True because to receive a pension you have to work for many years.

Domain false = {Students in a kindergarten class}

False because at 21 years old I shouldn't be in kindergarten anymore

c.) Every two people have the same mother.

True domain = {Twins in the world}

True because the twins have the same mother.

Domain false = {Everyone in the world}

False because not everyone has the same mother

d.) No two different people have the same grandmother.

True domain = {Miley Cyrus and Dua Lipa}

True because Miley and Dua don't have the same grandmother

Domain 2 = {Two blood brothers}

False because two blood brothers have the same grandmother
