A Fire near Waco
Six years later, in an about-face, the Federal Bureau of Investigation(FBI) admits that federal agents fired tear gas canisters capable of causing a fire at the Branch Davidian compound near Waco, Texas in 1993. But the official said the firing came several hours before the structure burst into flames, killing 80 people including the Davidians' leader, David Koresh.
"In looking into this, we've come across information that shows some canisters that can be deemed pyrotechnic in nature were fired—hours before the fire started,” the official said. “Devices were fired at the bunker, not at the main structure where the Davidians were camped out."
The FBI maintains it did not start what turned to be a series of fiery bursts of flames that ended a 51-day standoff between branch members and the federal government. "This doesn't change the bottom line that David Koresh started the fire and the government did not," the official said. "It simple shows that devices that could probably be flammable were used in the early morning hours. "
The law enforcement official said the canisters were fired not at the main structure where the Davidian members were camped out but at the nearby underground hunker. They bounced off the bunker's concrete roof and landed in an open field well, the official said. The canisters were fired at around 6 a. m., and the fire that destroyed the wooden compound started around noon, the official said. The official also added that other tear gas canisters used by agent that day were not flammable or potentially explosive.
While Coulson denied the grenades played a role in starting the fire, his statement marked the first time that any U. S. government official has publicly contradicted the government's position that federal agents used nothing on the final day of the siege at Waco that could have sparked the fire that engulfed the compound. The cause of the fiery end is a major focus of an ongoing inquiry by the Texas Rangers into the Waco siege.

A.the canisters were fired at the main structure

C.federal agents fired tear gas canisters capable of causing a fire

New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients(营养物) and can also cause unpleasant side effects in some people. So it's up to consumers to decide whether the new fatfree products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat the can't be digested at all.
Normally, special chemicals in the intestines(肠) "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it's that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids(类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.
Olestra is a substance that makes foods 'fat-free while keeping them delicious.
