Question

Q4/ Which of the following explains what led to the successful implementation of the Montreal Protocol?

A- All of these led to the successful implementation of the Montreal Protocol.

B- The world's largest users of CFCs were also the countries likely to suffer the most consequences caused by CFCs.

C- Substitutes for CFCs are fairly easy to produce and can be used in place of CFCs in most applications.

D- Scientific evidence strongly supported the connection between CFCs and ozone problems.

Q5/ Some environmental problems, like the emission of carbon dioxide, increase as income in a country increases because:

A- carbon dioxide is a usable product and WTO rules will not allow efforts by an individual country to limit the production and exporting of carbon dioxide.

B- the cost of reducing these emissions is relatively high and the source of the problem is global rather than isolated to one or a few countries, so one country's efforts to reduce emissions will not be worth the expense.

C- the continued increase in carbon dioxide emissions is necessary if income related to production is to continue to increase.

D- there are no technologies that are effective in reducing the emission of carbon dioxide as the result of production.
