One example of us foreign aid is- economic sanctions. military training. low tariffs. free trade.

The correct answer is that one example of US foreign aid is military training to other nations, since both low tariffs and free trade import a commercial relationship with advantages for both trading countries (United States and the other country). On the other hand, economic sanctions are the example of international interventionism exercising police power rather than foreign aid.

Therefore, the fact that US helps with military training to other countries without obtaining any benefit in return is the only example of foreign aid on the list.
