张三:Sales of VCRs-videocassette recorders -will decline in the next few years because the saturation level among U.S. households has virtually been reached.
李四:Every year a greater number of popular feature films is released on cassette-at least 6 per month. Clearly VCR sales will remain constan t, if not rise.

which of following is the best logical evaluation of 李四's response to 张三's argument?

a. he cites evidence that, if true, disproves the evidence cited by 张三 in drawing his conclusion.
b. he points out a gap in the logic followed by 张三 in drawing his conclusion.
c. he cites an issue ignored by 张三 and which outweighs the issues raised by 张三.
d. he doesnt speak to 张三's point because he fails to raise the issue of whether VCR sales may be linked to sales of other leisure-related products.
e. he fails to responde to 张三's argument because he assumes that nothing will significantly retard the sale of VCRs, which was the issue that 张三 raised.



d 为什么错拉？难道电影产品不是other leisure -related products? VCR是机器，电影产品就是碟片。难道不可以这样理解么？
