[求助]逆命题的问题（谢谢NN的回答）

雪落无声

补充材料93说，since applied scientific research is required for technological advancement,many have rightly urged an increased emphasis in universities on applied research.But we must not give too little attention to basic research ,even though it may have no forseeable application,for tomorrow's applied research will depend on basic research of today.



if the statement above are true,which of the following can be most reliably inferred?


a.if future technological advancement is desired,basic research should receive greater emphasis than applied research


b.if basic research is valued in universities,applied research should be given less emphasis than it currently has


c,if future technological advancement is desired,research should be limited to that with some foreseeable application.


d.if too little attention is given to basic research today ,future technological advancement will be jeopardized.


e,if technological advancement is given insufficient emphasis ,basic research will also receive too little attention


基础研究导致应用科学发展，应用科学发展导致技术进步，能Infer什么？






答案是d,if too little attention is given to basic research today,future technological advancement will be jeopardized，做的时候一眼看就选了，也对的。但是想多了，这个可以看做是基础研究导致技术进步的逆命题吗？怎么个对法？



可能是我对逆命题的理解还不透彻，哪位NN帮帮忙？谢谢

paopao

conclusion: basic applied tech tomorrow--> basic tech today


so we can infer: no basic tech today--> no    applied tech tomorrow.


so D，逆否

雪落无声

conclusion: basic applied tech tomorrow--> basic tech today


i think,the conclusion is basic research -->tech advance


for discussion

paopao

A depends on B


so A-->B

cranberry

A     depends on b means b is indispensable for a,so when a then b.not b then not a

1.applied scientific research is required for technological advancement: Technological advancement-> applied scientific research;fficeffice" />

2.tomorrow's applied research will depend on basic research of today: applied scientific research-> basic research

A require B: A->B         A be required for B: B->A         A depend on B: A->B
