首先給我的是一道英文的離散數學題，我記得大概是這樣的：
1)Balance the budget or reduce the taxes that there will be more money available to fight the pollution
2)Do not balance the budget will not reduce the taxes
3)Do not reduce the taxes
Is the statement “ there will be more money available to fight the pollution “ right?
要求用英文先給出判斷，在解釋如何得到答案的。
（離散數學是大二時學的了，早不記得了，所以這題我答的不好。但是我覺得我給出的答題思路是對的：
P:Balance the budget
Q:reduce the taxes
R:there will be more money available to fight the pollution
1）P∨Q→R
2）﹃P→﹃Q
3）﹃Q
經過推理就可以判斷出給出的句子對不對了。
n. 聲明，陳述
