The red velvet ant is famous for having one of the most painful stings in the insect world. In fact, it is often called the cow killer ant, because its sting is said to be so terrible it could kill a cow. Neither one of these names perfectly suit the creature, because it is actually not an ant at all. The red velvet ant is a flightless wasp that usually takes over the nests of bumble bees and stays low to the ground. Only the female of the species has a stinger, but what a stinger it is! It is exceptionally large and packs one serious punch. While the sting is not deadly, save for those who might have an allergic reaction, it is a highly unpleasant sensory experience.

Compared to chain stores, local businesses spend 6 percent more on hiring local workers. Local charities report significantly higher donations from local businesses. In one town, United Way received most of its income from two local groceries, a hometown bank, and a handful of local specialty shops.

The new office building will house several different companies and employ an estimated 600 people. However, it will also bring in more traffic and possible crime to the area. Several local companies are competing for the contract to begin construction, which will not happen until late spring, after the ground has thawed. Studies show that crime accompanies traffic issues. The increase to traffic for the new building is estimated at 15 percent. This, combined with the increase in wait time for local services, such as lines at the gas pump and fast food drive-through lanes, is likely to cause an increase in small crime throughout the area.
Which piece of evidence best supports the idea that constructing a new office building negatively impacts local residents?
