During the period described, pesticide accidents or injuries were:

• A. No pesticide accidents or injuries occurred
• B. Pesticide accidents were common
• C. Data on accidents is incomplete
• D. There was one minor incident

Answer: (A)

The main idea here is interpreting what the period’s data actually shows about pesticide incidents. If the records for that time contain no entries for accidents or injuries, the most accurate conclusion is that none occurred during the period described. This assumes the description presents the complete scope of that timeframe, so there isn’t any documented incident to count.

That’s why this option fits best: it aligns with a period where the log shows zero events. The other possibilities require at least one documented incident or a note about missing records, which aren’t indicated by the description. If there were common accidents, or even a single minor incident, there would be at least one report in the data; and a note about incomplete data would only appear if the description explicitly mentioned gaps in recording.
