Hints

General

  • If you're not sure where to start, try counting the number of "branches" that are needed by any given conditional
  • Check out this tutorial on most Common Lisp conditionals (excluding case)
  • This page provides even more detail and also covers case

1. Picking a Pal

  • This task requires a multi-branch conditional
  • Remember that keywords are just special symbols always equal to themselves

2. In Their Natural Habitat

  • This task requires a multi-branch conditional
  • It may be worth looking into the order in which branches of this expression are evaluated.

3. And Now, We Feast

  • This task requires a two-branch conditional

4. A Code of Conduct

  • This task requires single-branch conditionals
  • One action is unfitting when pet is a particular pet
  • The other action is unfitting unless pet is a particular pet
  • For comparing two strings for equality, the equal or string= functions can be used (you'll see more about this in the Equality and Strings concepts)
