Final answer:
Odd interstate numbers running north-south is true; Southern redeemers did not hope to preserve Republican rule, that's false; and the displacements for both individuals walking different paths but same start and endpoints are equal, also false.
Step-by-step explanation:
The statement 'odd interstate routes run primarily north and south' is true. In the United States, interstate highways that have odd numbers are designed to run primarily north-south. Conversely, interstate highways with even numbers are meant to run east-west. This system helps travelers understand the general direction of the highway just by knowing its number. For example, Interstate 5 (I-5) runs from the Canadian border down to the Mexican border along the West Coast of the United States, primarily in a north-south direction.
Regarding the statement from Exercise 17.4.2, 'Southern redeemers hoped to preserve Republican rule in the South', the answer is false. Southern redeemers were a political coalition in the post-Civil War southern United States that sought to oust the Republican coalition of freedmen, carpetbaggers, and scalawags. They aimed to regain political power and enforce white supremacy.
As for the true-or-false question about displacement, 'A person walks 2 blocks east and 5 blocks north. Another person walks 5 blocks north and then two blocks east. The displacement of the first person will be more than the displacement of the second person.', the answer is false because displacement is a vector quantity that depends only on the initial and final positions. Since both individuals start and finish at the same points, their displacements would be equal regardless of the path taken.
