Answer:
risk, resource
Explanation:
Difference in risk level and resource requirements affect choice of market entry.
Market entry is affected by risk level, for example if after researching real estate business in a city, an investor finds out that most people build their own homes. Real estate might be a risky business to start as the market for people looking to buy houses will be low.
Also looking at resource requirement, if one wants to set up a micro finance bank, and regulatory requirements dictate a level of capitalisation. If the business does not have funds available it will prevent entry into the market.
