Thank you so much! Watched and read lots on this and couldn’t understand until you explained with the H20 example.

At 4:55 the answer can also be correct because electrocution also means severe injury due to electric shock and there are evidence out there that people who got electric shock are alive. Other necessary conditions could be: time person was in contact with electricity, amount of electrocution and other environmental condition like humidity etc. are also necessary. Although, after mussing for sometime I was ready to accept the answer provided by you sir. Wonderful video :)

I didn't understand the part when you said "Oxygen is a necessity cause for water". Yes, one atom of oxygen is present in every molecule of water and the attributes of water are different from - not reducible to - the attributes of oxygen and hydrogen, but is oxygen really the CAUSE that water exists?

Some of these are straight up wrong.

Electrocution is not a sufficient condition for death. People can survive electrocution. Being electrocuted is not enough on its own to conclude that a person is going to die as a result. Terrible example.
