If ◻sled ~ ◻park which of the following statements are incorrect?
◻leds ~ ◻arkp;
◻edsl ~ ◻rkpa;
◻dsle ~ ◻kpar;
◻dels ~ ◻karp;

The first letter matches with the first letter. In Sled, the S equals the P. The L equals the A. The E equals the R. The D equals the K. For the last set, D does equal K because they are both the last letters. E does not equal the A because the E is the third letter, but the A is the second letter. So the last one would be incorrect. Hope this helps! ;)
