question 1
1 pts
true of false: the development of unconventional hydrocarbon reserves invalidated the concept known as peak oil (a.k.a. hubberts peak).
true
false

question 2
1 pts
the production of which of the following metals has become a critical issue for addressing sustainability goals?
chromium
carbon
steel
lithium

Explanation:

• Question 1: Peak oil (Hubbert's peak) is a theory about the point in time when oil production reaches its maximum and then starts to decline. The development of unconventional hydrocarbon reserves (like shale oil) has increased the total amount of recoverable oil resources but does not invalidate the concept of peak oil. The peak just gets adjusted to a higher production level (if more resources are found and exploited efficiently), but the basic idea of production having a peak (due to finite resources, even if those finite resources are larger than previously thought) still holds.
• Question 2: Lithium is crucial for batteries used in electric vehicles and energy storage systems. As the world moves towards more sustainable energy sources (like renewable energy which needs energy storage) and electric transportation (to reduce carbon emissions from the transportation sector), the production of lithium has become a critical issue. Chromium is mainly used in steel alloys for corrosion - resistance etc., carbon (in the form of graphite in batteries is also important but the question asks about metals, and carbon is a non - metal in this context), and steel is a widely used construction and manufacturing material but not as directly tied to current sustainability goals (in the context of new - age sustainable energy and transportation) as lithium.

Answer:

• Question 1: B. False
• Question 2: D. Lithium
