【答案详解】综合分析题。题干问的是“下列哪个最适合作为本文的标题?”根据定位句分别得出四个选项：A项“加州立法议员在周四投票决定将合法购买烟草的年龄从18岁提高到21岁。”；B项“加州立法委员会的投票是在旧金山将合法购买烟草产品年龄提高到21岁之后进行的。”；C项“加州将成为继夏威夷之后第二个提高购买香烟和其他烟草产品合法年龄的州”；D项“该项法案遭到了许多共和党人的反对”。B，C，D三个选项都是具体的表现并不能全面概括文章的主旨，故选A。

【难句解析】
①A week ago，the California Assembly approved the measure，wllich-in addition to raising the age limit--treats electronic cigarettes the salne as tobacco products，expands smoke-free areas，increases smoking bans and allows counties to collect higher taxes on cigarettes than the 87-cent per lmck state tax．
本句整体上是一个which引导的定语从句，同时使用破折号和in addition to来引导插入语。句式的变换保证了句意的完整，也避免了表达的缺漏。
②But supporters of the bill say raising the age to 21 moves legally purchased tobacco that much farther from younger kids．
本句从句部分的主语是现在分词短语raising the age to21，谓语是动词词组move…from…，宾语为legally purchased tobacco。宾语部分的that可能会让人产生这也是一个宾语从句的误解，这里的that much实际上是一个词组，表示“那么”的意思。
