Dolphins
• The newest members of the U.S. military forces aren’t soldiers. They aren’t even human. They’re dolphins! Specially trained Atlantic bottle-nosed dolphins have arrived in the Persian Gulf to help check for mines, or underwater explosives, along Iraq’s coastline. Once they’re finished, ships will be able to safely transport food and medicine to the Iraqi people.
Makai and Tacoma Ready For Action
The dolphins, named Makai and Tacoma, were flown into the Iraqi port city of Umm Qasr by U.S. Navy helicopters Tuesday night. They were expected to begin searching for mines along with military divers on Wednesday, according to several news reports.

Work
• The dolphins, which came from San Diego, California, are are trained to place markers near the mines they find. They are taught to avoid touching or swimming to the mines, which might cause them to explode, said Navy Captain Mike Tillotson. While Tillotson said there was little risk to animals doing this kind of work, some animal activists are speaking out against the plan. They worry the dolphins could get hurt.
Underwater Helpers
A unit of 70 dolphins and 20 sea lions has been trained by the U.S. Navy to spot underwater mines and bombs in deep waters. The sea lions are trained to alert humans when they detect an intruding diver.
• This is not the first time dolphins have helped out U.S. military efforts. The Navy started using dolphins in the early 1960s, when researchers began looking into how the dolphins' sonar, their ability to identify objects based on sound waves, could be used to locate mines and do other underwater tasks. The dolphins returned to action during the Vietnam War and again in the 1990-1991 Gulf War
Generalization

• A. This generalization is valid. It is supported by facts and examples.
• B. This generalization is faulty. The reader made an error and did not re-read to check the facts.
