The answer is B. The order would be K N T S O. Kashmir can never be in fifth place as four others will succeed it. It's max position in the order of appearance will be 4

J...........T...S
......N....T
J K ...........S
................S O
...K.N

Hence
JKNTSO

No info of the other 2 boats, so they can be anywhere
Even both of them in the first and second, K can never be fifth. The other options, when we plug in 2 other boats can still be arranged accordingly

ANS: B

Exactly eight boats- Jewel, Kashmir, Neptune, Ojibwa, Pacific, Spain, Tornado, and Valhalla--arrived at a dock. No boat arrived at the same time as any other boat. The boats arrived in an order consistent with the following conditions:

Tornado arrived before Spain but after Jewel. - J ----> T ----> S
Neptune arrived before Tornado.  - N ----> T
Kashmir arrived after Jewel but before Spain. - J ----> K ----> S
Spain arrived before Ojibwa. - S ----> O

If Neptune arrived after Kashmir, which one of the following must be false?

(A)  Jewel was the second  of the boats to arrive. - WRONG. May or may not be so.
(B) Kashmir was the fifth of the boats to arrive. - CORRECT. POE helps. 
(C)  Neptune was the third  of the boats to arrive. - WRONG. May or may not be so. If P(or V) arrives before J which arrives before N then this is possible.
(D)  Ojibwa was the sixth  of the boats to arrive. - WRONG. May or may not be so. If P and V arrive at last then true or else false.
(E)  Spain was the seventh  of the boats to arrive. - WRONG. May or may not be so. If P and V arrive earlier than S then true or else false.

Since we need maximum number before from each statement we have to position each boat like as follows.
N / J ----> K ----> T ----> S ----> O 
Here N and K can also interchange.
Only P and V are left which we can place before or after N/J.

IMO Answer B.

Dooperman · Answer

As per the given statements ,

The certain sequence among 6 (out of 8 boats) is 
J K N T S O

Answer would depend on the position of V & P

(A) Jewel was the second of the boats to arrive.
Can be true if one of the remaining arrives before J

(B) Kashmir was the fifth of the boats to arrive.
Can't be true even if both the remaining ships arrive before J

(C) Neptune was the third of the boats to arrive.
Can be true if V, P arrive after N.

(D) Ojibwa was the sixth of the boats to arrive.
Can be true if V, P arrive after O.

(E) Spain was the seventh of the boats to arrive.
Can be true if V, P arrive before N.

Answer is B...assuming Valhalla and Ojibwa can arrive at any place would help. Focus on  must be  false is key.

Thus is a full LSAT logic game, so you're not likely to see something quite like this, even on the wacky new DI section. However, this involves two key ideas: 1) "drop-ins" and 2) number before/after. As others have pointed out, we have an order of J - K - N - T - S - O. But P and V can drop in anywhere in that order. That's why I call them "drop-ins": they can jump in anywhere and interrupt the stated order.

On a MUST BE FALSE, the four wrong answers COULD BE TRUE. Prove this by trying to find a way to make each one true. To do this, look at how many MUST be before or after a given element, and then adjust position as needed, using the drop-ins.

A) J = 2. Nothing MUST come before J, but we can make A true by placing a drop-in in 1. 
 B) K = 5.  Four boats come after K, so it can't ever be 5th. (The latest it could be is 4th.)  There's our answer! 
C) N = 3. Two boats must come before N, so it will be 3rd as long as we put our drop-ins later.
D) O = 6. O is the 6th in the list, so if we follow it with both drop-ins, this placement works. 
E) S = 7. Only one boat must come after S, so S can be 7th. This just means that our drop-ins will appear somewhere before the 7th spot.
