Explanation
Commercial paper is a type of money market security that is issued by corporations and financial institutions to raise short-term funds. Commercial paper has a maturity of less than one year, typically between 30 and 90 days. Commercial paper is unsecured, meaning that it is not backed by any collateral or guarantee. Therefore, commercial paper has the highest degree of risk for the investor among the four types of money market securities listed, as it depends on the creditworthiness and liquidity of the issuer. If the issuer defaults or faces financial difficulties, the investor may lose part or all of their principal. Commercial paper also has a higher interest rate than other money market securities to compensate for the higher risk.
The other types of money market securities are:
Bankers' acceptances: These are negotiable instruments that are issued by a bank on behalf of a client who needs to finance international trade transactions. Bankers' acceptances have a maturity of less than one year, usually between 30 and 180 days. Bankers' acceptances are secured by the bank's guarantee and the underlying goods or services that are being traded. Therefore, bankers' acceptances have a lower degree of risk for the investor than commercial paper, as they are backed by the bank's creditworthiness and the value of the trade transaction.
Treasury bills: These are short-term debt obligations that are issued by the federal government to finance its operations and programs. Treasury bills have a maturity of less than one year, usually between 3 and
12 months. Treasury bills are considered risk-free investments, as they are backed by the full faith and credit of the government. Therefore, treasury bills have the lowest degree of risk for the investor among the four types of money market securities listed, as they have virtually no default risk or liquidity risk.
Treasury bills also have the lowest interest rate among the four types of money market securities, as they reflect the risk-free rate of return.
Municipal short-term paper: These are short-term debt instruments that are issued by municipalities or other local governments to finance their capital projects or operating expenses. Municipal short-term paper has a maturity of less than one year, usually between 30 and 270 days. Municipal short-term paper is secured by the taxing power and revenue sources of the issuing municipality or government.
Therefore, municipal short-term paper has a lower degree of risk for the investor than commercial paper, as it is backed by the ability and willingness of the issuer to levy taxes and collect revenues.

Explanation
A Canadian equity index fund is a type of mutual fund that invests in stocks that track a Canadian equity market index, such as the S&P/TSX Composite Index or the S&P/TSX 60 Index. These indices measure the performance of the largest and most liquid companies listed on the Toronto Stock Exchange (TSX). A Canadian equity index fund aims to replicate the returns of the index it follows, before fees and expenses.
Therefore, this type of fund would be best for Karen, who has a long time horizon, is comfortable with risk and volatility, and is primarily interested in growth. She also wants a mutual fund that will closely match what she sees on the TSX. References: CIBC Canadian Equity Index ETF, Top Canadian Index Funds of 2023 | The Motley Fool Canada

Explanation
Thomas must contribute to CPP based on his pensionable earnings, which are his income from employment or self-employment that are subject to CPP. However, he can deduct a basic exemption amount from his pensionable earnings, which is $3,500 for the year. Therefore, his contributory earnings are:
16,0003,500=12,500
The CPP contribution rate is 5.95% for employees and self-employed workers. Therefore, Thomas must contribute:
12,500×5.95%=743.75
