"Precondition" necessary condition modifier in LR bible 2018

[lathlee]

Hi, in the new LR bible 2018, the word "Precondition" is listed as a necessary condition modifier. can you introduce me one recent LSAT test LR that used such word to express conditionality? also, can you provide me one example of such a sentence consists of "precondition" ?

Hi Lathlee,

Sure, here you go:

• Example sentence: " A cease-fire is a precondition for us to negotiate."
  
  Diagram: Negotiate Cease Fire

Several example usages:

• PT52, September 2007, LR2, #15
  PT42, December 2003, LR1, #19
  PT23, October 1997, LR1, #19 (in the correct answer)
  PT17, December 1995, LR2, #1 (in the correct answer)

It's appeared elsewhere too, and is a word they expect you to understand

Thanks!
