Passage Summary: Generic drugs use the same main ingredients as big brands but are cheaper to make, so they work just as well and save you money.

Conclusion: Generic drugs are equal in effectiveness to brand-name drugs but are cheaper for the consumer.

Reasoning: Generic drugs share identical active ingredients with brand-name versions and have lower production and marketing costs.

Analysis: The argument assumes that 'active ingredients' are the only factor determining effectiveness. To strengthen this, we need to bridge the gap between having the same active ingredients and being 'just as effective' overall. Look for an answer that confirms inactive ingredients or manufacturing processes don't negatively impact the generic version's performance. Strengthening the link between the chemical makeup and the actual medical outcome is the key here.
