third option seems dangerous

ash2326 · Answer

But do confirm it with someone else @sara1234

anonymous · Answer

i think its either the first or third?

ash2326 · Answer

I also think it's third
I meant that giving adrenaline to a carnivores is dangerous, that's why it could be impractical

jfraser · Answer

three of the 4 optiosn are fairly easy to measure: brain waves (with an EEG or some other machine); time (with a stopwatch); gender (obvious). They are also completely objective outcomes. There will be no discussion among scientists whether a response time of 4 seconds is less than a response time of 3 seconds. The results obtained by these 3 experiments will not vary when different people perform each experiment and then later compare data.

The "quality" of a song is a subjective description based on the prejudices of the one interpreting the song. No 2 people are guaranteed to judge the "quality" of a song the same way. Option 2 isn't a scientifically-supported hypothesis
