  gmat邏輯測驗的難點在於,考生必需具有較強的邏輯推理才能,且在碰到分歧範例的標題時可靈巧應用gmat邏輯推理的各類解題辦法來舉行剖析息爭答。如下將經由過程兩個實例來向眾人先容幾個gmat邏輯推理題目標解題技能。

  詳細實踐兩道題:

  Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.

  (解釋:priced out of the market:因價高而被擠出市場)

  Which of the following statements, if true, would most weaken the argument above?

  (A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.

  (B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

  (C) Employers often hire extra help during holiday and warm weather seasons.

  (D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.

  (E) The teenage unemployment rate has occasionally declined in the years since 1960.

  看完題目,發明是減弱題;再讀原文,意思不難,很快提煉出其邏輯為

  假如國會制訂更低的teenagers最低人為 ===》teenagers的賦閑率將再也不上升

  明顯,準確選項起首要觸及最低人為和賦閑率之間的幹系,而其他內容則為無關信息,可以消除

  明顯A和B都是相幹的

  而C在談季候題目,D和E沒有觸及賦閑率快慢的緣故原由,都與原文邏輯無關,統統消除。

  以是只須要細心審閱A和B

  A “最低人為上升的時刻,賦閑率上升”,這與原文邏輯(更低人為將致使賦閑率不上升)構成了“反因反果”的幹系,所所以增強。(好比:“不長跑的人不長命”增強了“長跑的人長命”)

  如許A就被排除

  以是謎底只能是B

  在gmat邏輯推理題目標解題過程當中,考生除要熟知一樣平常的邏輯解題思緒外,還須要靈巧應用各類gmat邏輯推懂得題技能,而這類技能是考生在大批習題中造就起來的做題感到。考生依附這類感到可以快速將一些與標題無關的選項消除,從而找出準確謎底。
