Considering that nearly 85 percent of corn crops are genetically engineered, which impact does genetically engineered corn have on human health?
Only positives can come from this type of technology, as seen in the DDT study.
Human health will not be affected because scientists have studied this technology for over 50 years.
The genetically engineered corn has been proven to cause cancer in some human populations.
The long-term effects are unknown and have not been studied because it is a fairly new technology.

Best choice: "Human health will not be affected because scientists have studied this technology for over 50 years." — with an important clarification.

Why: Extensive research and regulatory review over several decades find that genetically engineered (GE) crops currently on the market, including GE corn varieties, have not been shown to cause harm to human health. Major reviews by bodies such as the World Health Organization, the U.S. National Academies, the American Association for the Advancement of Science, and the European Food Safety Authority conclude that approved GE foods are as safe as their conventional counterparts. No credible evidence links GE corn to cancer in humans. Safety assessments are done case-by-case (toxicity, allergenicity, nutritional composition), and monitoring continues.

Why the other options are incorrect:
- “Only positives…as seen in the DDT study”: DDT is an example of a chemical later found to have serious harms; it’s not an appropriate analogy and you can’t assume only benefits from any technology.
- “Proven to cause cancer”: This is not supported by credible scientific evidence.
- “Long-term effects are unknown and have not been studied because it is a fairly new technology”: GE approaches have been studied for decades and GE foods have been on the market for ~30 years; while science always monitors for new findings, they are not unstudied.

If you’d like, I can cite specific review reports or summarize the safety evidence for Bt corn and herbicide-tolerant corn.
