正确答案：A
推理题。第一段第一句提到，市政府关于在餐馆和酒吧的禁烟令虽然是极具争议性的，但是统计数据表明它们非常有效。所以[A]“市政府关于在餐馆和酒吧的禁烟令是有效的”是对文意的正确阐述，故为答案。第三段中提到，Scribbler50的贴激发了博客名为PalMD的医师上周对禁烟的有效性进行调查的灵感。由此可知，[B]“Scribbler50自己对禁烟效果进行调查”是错误的阐述，故排除；第六段中提到不是所有反对吸烟的标语都同等有效，而要看针对谁，有时候一条病态的警告恐怕会适得其反，所以[C]“ChristianJarrett发现有关吸烟的病态标志很重要”是错误的阐述，故排除；最后一段中提到，一些地区已经限制和孩子在一起的父母在车内抽烟，但还没有看见有关评估这些结果的报告，可知[D]“禁止家长和孩子在汽车里吸烟的方法很有效”是错误的阐述，故排除。
