In what year did the number of pesticide-resistant species first reach 150?

Explanation:
This question tests reading a time-series to find when a value first hits a target. To answer, look at the trend over years and identify the earliest year where the count of pesticide-resistant species reaches 150 (or more). In this data, the numbers are below 150 in the earlier years, and in 1983 the count reaches 150 for the first time. After that year, the counts stay at or above 150. So 1983 is the first year the threshold is reached.
