16 multiple choice 2 points

• chernobyl experiences nuclear disaster.
• chlorofluorocarbons (cfc) deplete the ozone layer.
• rivers and seas are polluted throughout the world.

which conclusion can best be drawn from these statements?
○ modern technology can have serious negative effects.
○ todays environment renews itself.
○ only developing nations have environmental problems.
○ most environmental problems originate in europe.
17 multiple choice 2 points
fossil fuels such as oil and coal are formed from
○ geological processes that transform organic materials
○ the rapid decay of animal bones
○ organic processes that lead to the fossilization of animal tissue
○ artificial processes used to treat and reuse garbage

Explanation:

• Question 16:
• The Chernobyl nuclear disaster is a result of modern nuclear technology.
• Chlorofluorocarbons (CFCs) are a product of modern industrial technology.
• Pollution of rivers and seas is often due to modern industrial and technological activities (e.g., industrial waste disposal).
• These examples show that modern technology can have negative impacts on the environment and human - related disasters.
• The second option “Today’s environment renews itself” is not supported as the statements show problems, not renewal.
• The third option “Only developing nations have environmental problems” is wrong as these are global issues (e.g., ozone layer depletion is a global problem).
• The fourth option “Most environmental problems originate in Europe” is incorrect as the Chernobyl example is in Europe, but CFCs and river/sea pollution are global.
• Question 17:
• Fossil fuels like oil and coal are formed from geological processes that transform organic materials (such as the remains of ancient plants and animals) over millions of years.
• The second option “the rapid decay of animal bones” is incorrect as it is a slow geological process, not rapid.
• The third option “organic processes that lead to the fossilization of animal tissue” is too narrow (fossil fuels also come from plant matter and it's a geological, not just organic process).
• The fourth option “artificial processes used to treat and reuse garbage” is wrong as fossil fuels are natural geological formations.

Answer:

1. Modern technology can have serious negative effects.
2. geological processes that transform organic materials
