Explanation
A yield curve is a graphical representation of the relationship between the interest rates (or yields) and the term to maturity of different fixed income securities, such as bonds or debentures. A normal yield curve is upward sloping, meaning that the interest rates increase as the term to maturity increases. This is because investors typically demand higher compensation for lending their money for longer periods of time, as they face more uncertainty and risk. Therefore, a normal yield curve implies that short term rates are lower than long term rates.

Explanation
Implied needs of your clients are needs reflected by statements made by clients regarding problems and dissatisfactions1. For example, a client may say "I'm worried about outliving my savings" or "I don't understand how this investment works". These statements imply that the client has a need for retirement planning or financial education, respectively. Implied needs are different from explicit needs, which are statements of wants and needs made by clients1. For example, a client may say "I want to save for my child's education" or "I need a low-risk investment". These statements express the client's goals and preferences clearly. Statements made by you showing readiness to solve a client's problem are not implied needs, but rather responses to implied needs1. For example, you may say "I can help you create a retirement plan that suits your lifestyle" or "I can explain how this investment works and what are the benefits and risks". Statements made by clients expressing the desire for lower commissions are not implied needs, but rather objections or concerns that may arise during the sales process2. For example, a client may say "Your fees are too high" or "I can get a better deal elsewhere". These statements may indicate that the client is not convinced of the value of your service or product, or that they are trying to negotiate a lower price.
