CR進階（一）：常見障礙之簡易診斷
請先試著做做這題，正確答案八選一。剩下七個選項都要思考「是什麼類型的錯誤」。
Indonesia has long been shadowed by its growing problem of drugs abuse. To deter people from selling drugs, the country’s National Narcotics Agency has suggested the punishment that Drug dealers in Indonesia will be made to eat their own supply until they die.
Which of the following, if true, would most seriously call the suggestion above into question?
(A) some seriously abused drugs, such as Methcathinone, are not banned in Indonesia.
(B) If Indonesia successfully tackled the drugs abuse, the GDP of Indonesia will significantly drop by almost half.
(C) Drugs dealers in Indonesia are generally not aware of the lethal effect of excessive drug intake.
(D) The rate of drugs abuse in Indonesia is much higher than in Philippine.
(E) Indonesia government believes that they will tackle traffic congestion with priority to drugs abuse.
(F) The problem of drugs abuse can be solved by treatments to drug addicts.
(G) The average price of drugs in Indonesian black market has been soared to a level that most drug addicts cannot afford.
(H) Unlike lethal drugs such as heroin, some drugs, such as LSD, are not lethal to human.
答案（反白後觀看）：C
障礙一：抓結論
本文的結論是：To deter people from selling drugs, the country’s National Narcotics Agency has suggested the punishment that Drug dealers in Indonesia will be made to eat their own supply until they die. 結論的主題在目的「阻止人們販賣毒品」。
抓不到結論的請參考：CR基礎（一）：如何找到結論句？
障礙二：預測思路
障礙三：基礎錯誤初步篩選
B、E：這兩個選項是「主題無關」。
如果選到B/E，代表沒有意識到結論主題與選項重點的關聯。既不是B的「對GDP的影響」，也不是E的「塞車問題」。結論的主題只有一個，就是「阻止販賣毒品（方案的目的）」。
D：無關比較。
如果選到B/E，沒有注意到文章討論的主角僅有一個「印尼」。
F：他方案無關。
方案類型的題目跟因果類型的題目不同。就算別的方案成功了，不代表我的方案會失敗。
以上四個選項若是選錯或者不選但卻不能說出明確的錯誤理由，請參考：CR基礎（三）：選項初步篩選
障礙四：混淆選項抉擇
A、H：故意有點出相關因素，但方向相對不確定。
