Final answer:
An economic depression implies a severe downturn with a significant decline in income and employment. Moreover, a rise in supply in the financial market generally causes a decline in interest rates.
Thus the correct answer is C) Depression.
Step-by-step explanation:
The question 'A negative altitude in astronomy or an economic woe' refers to conditions of decline within two distinct contexts: astronomy and economics. Given the options provided, the term that best fits the described scenarios is depression. In an astronomical sense, negative altitude is less commonly used, but the concept of a depression in economic terms is well-defined.
A depression is a severe and prolonged downturn in economic activity. It is characterized by a significant decline in income and employment, which exceeds the severity and duration typically associated with a recession. In astronomy, while the term isn’t standard, the concept might loosely be related to a feature that is lower in altitude relative to the surrounding area, such as a crater on the Moon's surface, but this is not the primary context of the term in this case.
A change in the financial market that would lead to a decline in interest rates is generally a rise in supply of money or credit. When supply increases while demand remains the same or decreases, the price of borrowing money, which is the interest rate, tends to go down.
Thus the correct answer is C) Depression.
