Question 4 @ 2024-01-16 18:35

Here’s a dad-joke:

• Why is “abbreviated” such a long word?

There’s a whole bunch of these things:

• Why is “short” longer than “long”?
• Why is “big” smaler than “small”?
• Why is “syllable” longer than “word”?
• Why is “million” the same length as “hundred”?

What makes these sentences funny (at least in a dad-joke-sense)?

---

• A They put contrasting words into the same context.
• B They misuse quotation marks.
• C Scare quotes are always funny-ish.
• D They confuse syntax and semantics.
• E This question is in no way related to PL and therefore deserves no answer.

Question 5 @ 2024-01-16 18:38

You’re about to spend some time on a deserted island, doing list-related activities. You’re given null, and the two accessor functions car and cdr (or first and rest). In addition to that you need one more constructor function to make lists: which one should you choose?

Some reminder expressions that return the same list:

---

• A cons, because it’s the list cons-tructor.
• B cons, because it’s the most versatile.
• C list, because it’s the obvious constructor for lists.
• D list, because it’s more convenient to use than cons.
• E append, because it’s more powerful.
