问题如下：
National Plastics Corp. is
a leading manufacturer of high-quality injection-molded plastic packaging
materials used by various industries, primarily food and beverage processing
and packaging firms.
On 4 January 2013,
Haines Foods, Inc., launched a hostile takeover bid for all of the shares of
National at $30 per share (a $5 premium in excess of the pre-bid price). Haines
Foods is a national distributor of deli and dairy products. If its bid is
successful, it plans to continue to operate National as a wholly owned
subsidiary.
If Haines Foods is
successful in its attempt to acquire National Plastics, the business
combination is best classified as which type of merger?
选项：
A. Vertical, backward
Horizontal, conglomerate
Vertical, forward
解释：
If Haines acquires National, it would be a vertical merger because they are both in the same production chain. It is an example of backward integration because Haines is closer to the consumer than the packaging manufacturer.
老师好 怎么判断 上下游？ 不是一般都是食物 都是 先食物 再包装 （比如工厂里 用苹果做例子， 先摘苹果，机器筛选，然后在洗，最后再包装的吗？）， 这样的话 相当于食物是原材料，包装离客户更近了吗？ 那就是H 是上游， N 是下游 于是就是vertical ,forward.
是不是考试的时候 题目里会说清楚 东西生产的流程？
谢谢。
