Question

1 multiple choice 20 points a material is biodegradable if it is made of synthetic material. it is made from petroleum or natural gas. it can be broken down by biological processes. if can be disposed of in a landfill. 2 multiple choice 20 points decisions made by the current generation can open or limit possibilities of future generations. will not limit any possibilities for future generations. should not include considerations of possibilities of future generations. should only be concerned with opening possibilities for future generations.

Explanation:

1. Biodegradable materials are those that can be broken down by biological processes (such as the action of bacteria, fungi, etc.). Synthetic materials (often non - biodegradable), materials from petroleum/natural gas (many plastics), and landfill disposal (not related to biodegradability mechanism) are incorrect.
2. Decisions of the current generation can have long - term impacts. They can open new opportunities (e.g., investing in renewable energy research) or limit (e.g., over - exploiting non - renewable resources). Considering future generations' possibilities is important (so options that ignore or only focus on one aspect are wrong).

Answer:

1. it can be broken down by biological processes.
2. can open or limit possibilities of future generations.
