OG-77, OG-165

1．come to含义？为什么用现在完成时？
77. Though the term "graphic design" may suggest laying out corporate brochures and annual reports, it has come to signify a wide range of work, from package designs and company logotypes to signs, book jackets, computer graphics, and film titles.

2．中心词是incomes还是household?

从句子结构分析，中心词应该是incomes，但如果是这样，那意思不就成了社区中家庭收入的49%低于贫困线以下，逻辑不通。感觉应该表达的是社区中49%户，其家庭收入低于贫困线，可是中心词又不是household。  
165. At Shiprock, New Mexico, a perennially powerful girls' high school basketball team has become a path to college for some and a source of pride for a community where 49 percent of the household incomes are below the poverty level.

2、是否可以理解为49%的家庭的收入？
1、这里的考点不是是否用完成式，而是主谓一致等。其实英语中也有很多特例是很难全部解释清楚的，在考试时，只能就考点而发现差异。
