Good point. I wouldn’t expect a human to need the last sentence.
You should be able to easily accept answers like "four" and "4" as equivalent, for example. I doubt there will be that many frontier models running against this test at any time, and a simple glance at the answers from any human should be enough to catch edge cases like this one.
Yeah, but i bet many humans would answer a question like this by naming the number and then listing the tendons. Just writing down a single number to a question worded like that (without the last sentence) feels wrong.
The question goes into too many details and explains too much for that. People mirror the style of the question with their answer. They asked a mini essay so i will answer with a mini essay of my own. If they would have wrote “Number of tendon pairs attached to sesamoid bone of hummingbirds?” Then i would write a single number, no explanation.
