Each of the following is a major source of great wealth except __________.( \(\mathrm{O2})\) a) earning large salaries b) starting up new companies c) owning real estate d) receiving an inheritance

First, let's look at each option one by one and discuss whether it can lead to great wealth or not: a) Earning large salaries: High salaries can generate wealth, but it may take longer to accumulate significant wealth compared to other options like starting a successful company or investing in real estate. Therefore, this option alone may not generally be considered as a substantial source of great wealth. b) Starting up new companies: If a new company becomes successful, its founders can indeed accumulate considerable wealth quickly. Many billionaires have achieved their wealth through successful start-ups. So this option can be a major source of great wealth. c) Owning real estate: Investing in real estate properties can lead to substantial wealth over time, as property values increase and rental income is generated. Real estate has played a significant role in building wealth for many individuals. It is considered a major source of great wealth. d) Receiving an inheritance: Inheriting wealth from family members or relatives can lead to great wealth if the inherited assets (e.g., properties, investments, stocks) are significant. Receiving an inheritance is also considered a major source of great wealth for some people.

Based on the analysis in Step 1, we can conclude that option (a) earning large salaries might not be a major source of great wealth as it takes more time to accumulate wealth in comparison to the other three options. Therefore, the answer is: (a) earning large salaries
