[Helr题库] prep一道题

Noting that the Federal Reserve had raised a key short-term interest rate again last month, analysts said that they expected orders for durable goods to decline soon because rising interest rates makes it more expensive to buy them on credit

• Arising interest rates makes it more expensive to buy them on credit  
• Brising interest rates make buying on credit more expensive  
• Ca rise in interest rates make it more expensive to buy on credit  
• Da rise in interest rates make buying on credit more expensive  
• Ea rise in interest rates makes it more expensive for them to be bought on credit 这道题的正确答案是B，但是当时看题的时候一下子就排除了BCD，因为我觉得make应该是makes，因为不管前面是rising还是a rise跟的动词都应该是单数形式，难道不对吗？求大神解释~
