Neighborhood blog post on Saturday morning: During the past 5 days, traffic was bad on Wednesday, worse on Monday, and better on Tuesday than on Wednesday. Also, traffic was better on Friday than on Thursday. Assume the blog post is accurate. Select for Could determine worst the statement that, if added to the post, would make it possible to determine which of the 5 days had the worst traffic, based on the information given in the post. Select for Could determine best the statement that, if added to the post, would make it possible to determine which of the 5 days had the best traffic, based on the information given in the post. Make only two selections, one in each column.

Let >> suggest better than 1. During the past 5 days, traffic was bad on Wednesday, worse on Monday, and better on Tuesday than on Wednesday. The relation on the traffic on three of the days is Tuesday >> Wednesday >> Monday 2. Also, traffic was better on Friday than on Thursday. The other two days are related as Friday >> Thursday Our answer will come when one from each is connected through some relation to make the chain clear. The question can be answered without looking at options. Worst traffic: worst traffic will be either Thursday or Monday. If Thursday is better than any of the three in (1), Monday becomes worst and if Monday is better than Friday then Thursday becomes worst. Only option 1 fits in any one of the two situation. Thursday >> Monday So Monday is the worst. best traffic: Best traffic will be either on Tuesday or Friday. If Thursday is better than Tuesday in (1), Friday becomes best and if any of the three in (1) is better than Friday then Tuesday becomes best. Only option 5 fits in any one of the two situation. Friday << Tuesday So Tuesday is the best.

I believe a good method here is to visualise the days of the week. 2 relations are given: 1. Best --------------------> Worst Tuesday → Wednesday → Monday 2. Best --------------------> Worst Friday → Thursday To find the best here, we either need to make tuesday the best, or friday the best. Lets try with each option: A: Traffic was better on Thursday than on Monday Best --------------------> Worst Tuesday → Wednesday → Monday Friday → Thursday ---------- (For sure Monday is the Worst) B: Traffic was better on Wednesday than on Thursday. Best --------------------> Worst Tuesday → Wednesday → Monday Friday → ------------- → Thursday (Can't decide as 2 values at best and worst) C: Traffic was better on Friday than on Wednesday. Best --------------------> Worst Tuesday → Wednesday → Monday Friday → ---------- → Thursday (Can't decide as 2 values at best and worst) D: Traffic was worse on Thursday than on Tuesday. Best --------------------> Worst Tuesday → Wednesday → Monday Friday → ----------- → Thursday (Can't decide as 2 values at best and worst) E: Traffic was worse on Friday than on Tuesday. Best --------------------> Worst Tuesday → Wednesday → Monday --------- → Friday → Thursday (For sure Tuesday is the best)

I used a number line What we know ____M_______W_______T______ & _____ H ______ F_______ we do not know how H (Thursday) and F (Friday) compare to the other. used statements to place the remaining letters.
