That reminds me: During the oral exam for my Ph.D. (seems recent, but it’s longer ago than your birth in many cases), I was asked how to increase diversity in good quality habitat in a nature reserve. I responded, “Build a road through it!” The prof who asked hadn’t expected that! As I was explaining (including saying that biodiversity in itself isn’t necessary a good measure of habitat quality), I could see my major professor’s small smile. That question went well.
