Another critic is David McCarron, a nutrition and kidney disease expert at the University of California, Davis. He and his team looked at large studies of diets in thirty-three countries. They found that most people around the world eat about the same amount of salt. Most of them eat more salt than American health officials advise.Doctor McCarron says the worldwide similarity suggests that a person’s brain might decide how much salt to eat.Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute, a trade group for the salt industry. Doctor Alderman is a member of an advisory committee (咨询委员会). But he says he receives no money from the group. Doctor McCarron is paid for offering scientific advice to the Salt Institute.1.2.10 Michael Alderman is serving on an advisory committee for free.○ True○ False○ Not Given

我们来一步一步分析这个题目。

题目是：
Michael Alderman is serving on an advisory committee for free.
（迈克尔·奥尔德曼正在无偿地担任一个咨询委员会的成员。）

我们需要判断这个陈述是 True（正确）、False（错误），还是 Not Given（未提及）。

第一步：找出文中关于 Michael Alderman 的相关信息。

原文中提到：
> Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute, a trade group for the salt industry. Doctor Alderman is a member of an advisory committee (咨询委员会). But he says he receives no money from the group.

翻译：
> McCarron 博士和 Alderman 博士都与盐业协会（Salt Institute）有联系，这是一个盐业的行业组织。Alderman 博士是咨询委员会的成员，但他表示他没有从该组织获得任何金钱。

第二步：分析题干和原文的对应关系。

题干说：“Michael Alderman is serving on an advisory committee for free.”
意思是：他正在无偿地担任咨询委员会的成员。

原文明确说：“he says he receives no money from the group.”
即：他声称自己没有从该组织获得金钱。

这说明他没有拿钱，也就是无偿服务。

虽然原文用了“he says”（他表示），但题干只是陈述一个事实，而原文也明确记录了这个说法。在阅读理解题中，如果原文明确说某人声称某事，且没有其他信息反驳，我们通常接受这个信息为真。

因此，题干的陈述与原文信息一致。

第三步：判断选项

• True：题干与原文信息一致 → ✅
• False：与原文矛盾 → ❌
• Not Given：原文没有相关信息 → ❌（但原文其实有提到）

结论：

题干信息在原文中有明确支持，因此答案是 True。

答案：
\boxed{\text{True}}
