LG求大牛解惑

今日小弟在做powerscore Bible的LG部分的时候遇到一个困惑，请大牛们详解之，不甚感激。December 2006 questions 11-15：a locally knows guitarist's demo CD contains exactly seven different songs-S,T,V,W,X,Y,and Z.Each song occupies exactly one of the CD's seven tracks. Some of the songs are rock classics;the others are new compositions. The following condition must hold:
S occupies the fourth track of the CD. Both Wand Y precede S on the CD. T precedes W on the CD. A rock classic occupies the sixth track of the CD. Each rock classic is immediately preceded on the CD by a new composition. Z is a rock classic.
按照以上的条件，可以得知大致字母的顺序为T,W,Y在S之前，Z第六，V和X不定在5或7间游荡。根据powerscore的解释，由Both Wand Y precede S on the CD. T precedes W on the CD. 即可得知T在W之前，Y在S之前，同时W和Y皆在S之前。
我的问题就是：Both Wand 是什么意思？为何能得出T在W之前，Y在S之前，同时W和Y皆在S之前。这一结果？如果以后在考场遇到此类类似于“题眼”的单词认识应该作何处理？
多谢各位大牛

It means "Both W and Y"……

Whatever sketchy materials you're using must have accidentally eliminated the space between the variable "W" and the word "and".
