Amplify Benchmark

Will the properties of the two samples likely be the same or different?

• The properties will likely be different because the repeating groups of atoms that make up each sample are different.

• The properties will likely be different because there are more repeating groups of atoms in Sample 2.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have the same number of atoms.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have two of the same types of atoms.
