If Michael Moulton, the Creative Director of MoneyDesktop, decided to put up billboard puzzles to attract engineer applicants just in Utah, what would his greatest difficulty and biggest advantage be? Check all that apply.

1. Billboard advertising is considerably less expensive that other forms of advertising.

2. People might not have enough time to see the billboards as they drive by.

3. They wouldn't attract engineers with superior skills that live in other parts of the country.

4. Because the billboard ads were tied directly to the labor market, they would be likely to attract more qualified candidates.
