I have to agree. The old tests required nuance, but the answers to most of these questions are obvious. This feels like one of the easier HSK Beginner listening tests of old, not on the upper end of intermediate.
There was a study done on survival rates of cats falling from skyscrapers in Manhattan that found the survival rate of falls from the 9th floor or higher were 90%, but the 3rd floor to the 8th floor had much higher mortality rates. The suspected reason is that after the cat reaches terminal velocity, it will relax and spread out, which causes it to slow down. Impacting the ground in a relaxed state also helps spread the impact out. Most cats falling from the 9th story and up only suffered minor injuries such as cracked ribs, broken teeth, or broken legs.
@palafx I'm not entirely sure what grammatical purpose 了 performs in this sentence, but every single time I omitted it when trying to tell vendors that I wasn't interested, they would immediately correct me, so I made sure to always include it.
