单选题 A co - worker of mine recently recommended to do some research online before making my next purchase. As an elementary school teacher with a modest salary and a sizeable mortgage, cost was a major concern. While searching the Web I found a few online teeth whitening companies giving away free trials where you only had to pay a few dollars for shipping. I ordered two products, Dazzle White and Total White, both of which had 9/10 ratings and positive feedback from all users. After using the first product the results were noticeable, but after following with the second product I had a celebrity white smile. I'm far from a medical expert, but it appears that each product focused on DIFFERENT parts of the problem and that the second one put the whitening effect into overdrive. By using them both in a row I had absolutely unbelievable results. I can't believe companies are practically giving these products away!

• A. A not big salary with a great mortgage.
• B. Avery small salary to buy anything fancy.
• C. A not big salary with a moderate mortgage.
• D. A good salary with a great mortgag
