Broccoli is known to be a healthy vegetable. It contains vitamin C and vitamin K. A recent study shows that Broccoli has another health benefit. A “good compound”, it helps to prevent cancers.When cut up, the broccoli creates this good compound. When cooking broccoli, most people boil, steam, or microwave it. Some time ago, scientists tested these cooking methods. The scientists found out that boiling, steaming, or microwaving broccoli destroys the good compound.In China, stir-frying broccoli (and other foods) is popular. Researchers in China decided to test stir-fried broccoli.The researchers cut it up some broccoli into tiny pieces. They divided it into three samples.One sample was left uncooked. They immediately stir-fried the second sample for four minutes.Before stir-frying the third sample, the researchers waited 90 minutes. This gave the broccoli time to create the good compound.The researchers tested each sample for the good compound. The raw broccoli had the greatest amount. The after-90-minutes stir-fried broccoli had a large amount of the good compound. The sample stir-fried immediately had the least.The researchers recommend that cooks wait 30 minutes after cutting up broccoli. Then, stir-fry for four minutes. This, they say, makes the healthiest cooked broccoli.
Manager’s Con Answer: No, a country can never be fully prepared for an earthquake. Earthquakes can happen anytime without warning. Experts cannot know when they will strike. Some earthquakes can be very powerful. They can damage old and new buildings. People can have earthquake drills. Yet, it is still difficult if an earthquake hits in the middle of the night.
Manager’s Pro Answer: Yes, a country can be fully prepared for an earthquake. Earthquakes have happened many times before. Now, countries know how to prepare for an earthquake. They can build stronger buildings or houses. Also, governments can teach people what to do during an earthquake. They can teach them what emergency items they need to keep.
