Question
In this graph, the red bars correspond to the estimated number of years that these metals will remain economically recoverable, at current prices, given known global reserves, and assuming current rates of consumption. The entire bar in each case (red plus orange) shows the estimated number of years that these metals will available using current technology on all known deposits, even those that are not currently economically exploitable.
Use the graph to answer the following question.
If the demand for molybdenum doubled and no additional recoverable resources for this metal were found, we would run out of molybdenum in about ________ years.

To answer the question about the estimated time until molybdenum is exhausted if demand doubles, you would need to analyze the graph provided, which shows both the economically recoverable reserves (red bars) and the total reserves including those that are not currently economically viable (the full height of the bars).
Since I cannot see the graph, I can provide you with a general approach:
1. **Identify the length of the red bar for molybdenum**: This tells you how many years of molybdenum would remain at current consumption rates.
2. **Determine the impact of doubling the demand**: If the current demand is consuming the red bar's value over that many years, doubling the demand would effectively halve the estimated remaining years of economically recoverable reserves.
3. **Calculate the new estimated time**: Take the number of years indicated by the red bar and divide it by 2 to account for the increased demand.
Based on the given choices:
- If the red bar for molybdenum is, for example, 100 years, then doubling the demand would suggest that we only have about 50 years remaining.
Please review the graph to find the length of the red bar for molybdenum and use the approach outlined above to select the correct answer from the available choices (50, 20, 100, 140, 160).
