问题 There must be more Chinese staff at UNESCO in 2019 than in 2018 if the quota is raised. [br]  
The quota for Chinese staff at UNESCO is between 23 and 39 in 2018, but will likely be between 38 and 63 next year as China becomes the biggest contributor.
Light travels in waves. Every color we see is determined by the length of those waves. Red wavelengths are the longest, and as you go through the rainbow the waves get shorter and shorter until you reach the blues and violets, which are the smallest.
选项 A、True
B、False
答案 A
解析 语义辨析及特定信息的找寻与判断。根据原文“Red wavelengths are the longest…go through the rainbow the waves get shorter…blues and violets，which are the smallest”可知，从红光到紫光波长逐渐减小。题干涉及的两种颜色的光分别为橙光和绿光，根据彩虹颜色的排列，橙光更接近红光，而绿光更接近紫光，所以橙光波长大于绿光。因此，该题的说法是正确的。根据原文陈述推断比较关系。该题主要围绕波长与颜色的关系，关注描述性词，如“long” “short” “small”，以及与之相关的比较结构，结合常理，即可推理判断题干所述是否正确。
