Angela was instructed on a test to make an analogy, or comparison, for polymers. She writes four examples of how polymers are like pearl necklaces. She has many parts to this analogy that make sense, but one part of her analogy does not fit. Which is the most likely error in her analogy?

The pearls are like monomers.
The thread that connects the pearls is like an ionic bond.
The entire necklace is like a polymer, or macromolecule.
Stringing the beads onto the thread is like polymerization.
