Question

Read this prompt.

Create a multimedia presentation about the risk to farmers using standard farming methods such as pesticides, as compared to organic farming techniques. Use research and evidence to support your opinion. Use persuasive techniques and a variety of visual aids in your presentation.

What would be the most effective visual aid for this prompt?

a quote from a farmer discussing the difficult process of applying chemicals
a chart showing how commonly used chemicals negatively affect farmers' health
a map showing the number and locations of organic farms around the country
a photo of people enjoying fruits and vegetables grown on an organic farm

Answer 1

A chart showing how commonly used chemicals negatively affect farmers' health.

Why: the prompt asks for research- and evidence-based persuasion about risk. A well-designed chart communicates quantified, comparable health impacts (rates of illness, exposure levels, symptom frequency, cancer or neurological risk, etc.) far more clearly and credibly than an anecdote, a map of organic farm locations, or a feel‑good photo.

Tips to make it most effective:
- Use clear labels, units, and a concise title (e.g., “Incidence of Pesticide‑Related Health Outcomes Among Conventional vs. Organic Farmers”).
- Show meaningful comparisons (bars or grouped bars, or a line chart over time) and error bars/confidence intervals where possible.
- Include the chemical types and specific health outcomes (acute poisonings, chronic disease, reproductive effects).
- Cite reliable sources directly on the slide.
- Pair the chart with a short caption, a farmer quote for human impact, and a photo for emotional resonance to create a balanced, persuasive multimedia slide.
