If i decided to build a rope out of nothing. oh much nothing would there be? physiological test!

Nothing.. means "no thing", which means non-existent.

If nothing is non-existent, than the extent of even having "nothing" is non-existent, which means that the amount of nothing is not available. There would be no rope either.

hope this helps

i think the answer is c) ability to survive in high salinity.

hope it
