What is the best explanation for the changes in population and steel consumption during the last 50 years on the graph? People have grown to understand the effects of consuming too many resources and have used less steel in
their daily lives

Past construction of things like hydroelectric dams has continued to meet needs without requiring more
construction

We are running out of the matenals needed to make steel so there will be less and less used each year

Even though the population has decreased people are using more and more steel each year

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
