问题 What can be inferred from the first paragraph?
Why did the Americans agree to offer EU some technical help?

选项 A、EU promised to give US financial helps if US helps them technically.
B、EU’s new system is not strong enough to compete with that of the US.
C、EU agreed to slightly change the signals of their satellite system.
D、EU promised to slow down the launching of their satellite system.

答案C

解析 由题干中的Americans agree to offer EU some technical help定位到原文第二段第四句In return for the modification of Galileo’s signals,the Americans agreed to give Europe technical assistance in developing Galileo...[精析] 原文第二段第四句提到,作为对欧盟调整信号的回报,美国同意给予技术援助。可以推测援助的前提是欧盟调整信号。故C)“欧盟同意适当调整其卫星系统信号”正确。[排除干扰] A)中涉及的经济援助在原文没有提及;原文并没有对两者优劣做出判断,故排除B);欧盟同意减缓发射在原文中并未体现,排除D)。
