The answer is D because it reflects most on what the passage is about.
Answer:
Demand for recycled paper has increased as consumers have become more aware of the environmental issues surrounding waste disposal. Paper is a natural raw material made from renewable wood and plants. Recycled paper is made from waste paper and paperboard. Both new paper and recycled paper contain traces of heavy metals. However, some types of recycled paper contain more heavy metals than new paper due, in part, to the inks used for printing or adding color to the original paper. Metals can migrate from the paper packaging and containers used for food to the food itself. This metal migration is controlled and monitored to reduce the exposure of humans to heavy metals. Food agencies in each country determine the limit of cadmium, zinc, nickel, and copper in packaging materials. Most countries impose a limit of heavy metals in recycled paper not to exceed 100.0 ppm or 100.0 . The limit for lead in eggfruit, or vegetable-packaging is lower-not to exceed-20.0 mg/kg. The table in Figure a lists the results of the analysis of samples of recycled paper produced by a manufacturer during a three-month period. The goal of the manufacturer is to reduce the amount of heavy metals-especially lead-in the recycled paper it produces and sells. From March to May, the manufacturer varied the
methods of production each month to determine which method would produce paper with the lowest metal content. Each month, lab technicians cut small samples of recycled paper with an area of 1.000 and a thickness of 0.0500 The technicians then prepared the samples for analysis. The average density of the samples is Use the information provided in the figure to answer the
following questions:
a. Did the company reduce the amount of lead in its product between March and May?
b. Which metal was not reduced?
c. Each month's sample represents a different manufacturing process. Which process would you recommend the manufacturer choose to continue to use over the next year while additional processes are tested? Why?
d. What is the total amount of the five metals for the April sample (in mg/kg)?
e. What is the total mass (in mg) of the five metals for the April sample found in the 1.000 sample?
f. Lead has four stable isotopes: 204
Explanation:
so this problem gives us a lot of information and asked us to answer several questions. So, Letter A says, did the company make reduce the amount of lead in its product between March and May? And the answer is yes. The PB levels went from 3.5 to 2.8 22.4, so it was reduced. Be asks which medal was not reduced. And that would be sync because England from 2.723 point 2.723 2 to 3.7 so zinc increased. It was not reduced. See says each month sample represents a different manufacturing process.

Answer:The statement “No students should be expelled from school” has so little words but huge meaning to me. Although my opinion to agree or disagree with this statement truely depends on the situation, the tone and voice of this statement does not. I believe that this has a straight forward and set down tone. Almost making the statement seem like it's talking to you. Telling you what is right and what is wrong. It may be short and possibly underdeveloped but it does not hold back on the brain. Even with having an ever changing opinion on this topic I still can feel that essance of an answer coming from it. As if the statement it self is the answer regardless of what I have to say.
With my opinion not yet in hand I must say I agree with this statement. That no students should be expelled from school. For no reason at all unless it is a legal concern. Meaning that unless somebody’s rights are being taken away or violated in an illegal fashion this rule should always apply. Considering we as humans have many rights applying towards us such as the 1st amendment being Freedom Of Speech it's just apparent that this should apply to everyone. Not just my school or the nearest school but every school in the united states. So it's not just my opinion but the constitution and laws opinion that no student should be expelled, but thats only considering ONE of the many reasons to this opinion of mine. There are so many logical reasons as to why I 100% agree with the statement “No Students should be expelled from school.”

Now I know this is knowhere near perfect at all but I wrote this as fast as I could to prevent atleast getting an F.
