enry mixed salt and water together in a cup until he observed a clear solution. He measured the mass of the solution. Then he placed the cup outside for several sunny days during the summer. After a week, he observed that only solid salt remained in the cup and the mass had decreased. Henry concluded that a physical and chemical change occurred in this investigation. Which statements correctly defend or dispute his conclusion? He is correct. Dissolving salt in water is a physical change, but evaporating the water is a chemical change. Formation of a solid is evidence that a chemical change occurred. He is correct. Evaporation is a physical change, but dissolving salt in water is a chemical change. The change in mass is evidence that a chemical change occurred. He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change. He is incorrect. Dissolving salt in water and evaporation of the water are both chemical changes. The reappearance of salt is evidence that the change was reversible by a chemical change, so it could not be a physical change.

Read this excerpt from "herd about the flu." the flu shot prevent huge numbers of infections. even when it doesn't fully prevent infection in every person, the shot makes any flu infection less serious. on a global scale, the vaccine can reduce the number of infections only if most people in the community take it. that's because vaccines need to reach enough people to achieve a "herd immunity," the level of immunity needed to prevent the virus from spreading. if too few people get the vaccine, the people who receive it may not be well protected against infection. so the next time you are at the drugstore, and you see no flu shots available, think about the reasons behind it. drug makers are scared to make too many flu shots because they could lose too much money. they then make fewer flu shots and the effect of the flu shots becomes weaker because not enough people take it. people become more reluctant to take the flu shot since they don't think it will fully work. the demand goes down further and the flu companies make even fewer shots the next year. this could continue until the community changes its mind and we all get the flu shot. "that is a community responsibility," says the president of merck, one of the two remaining flu vaccine manufacturers. which argument best supports the passage's claim that more people should get the flu vaccine to stop the virus from spreading? 1.if too few people get the vaccine, the people who receive it may not be well protected against infection 2. so the next time you are at the drugstore, and you see no flu shots available, think about the reasons behind it. 3.people become more reluctant to take the flu shot since they don’t think it will fully work. 4.drug makers are scared to make too many flu shots because they could lose too much money.
