Question

In 1–2 sentences, summarize the innovation you believe was most important and why: the invention of DDT, the polio vaccine, or the creation of the internet. Use at least two pieces of evidence to support your argument

Answer 1

The creation of the polio vaccine was the most important innovation of the three mentioned because it virtually eradicated the disease, saving countless lives and preventing lifelong disabilities. The development of the vaccine by Dr. Jonas Salk in 1955 led to a dramatic decrease in polio cases worldwide and paved the way for other successful vaccinations.
