Last minute Dr. Collins errata thread.

Saw the same, definitely a mistake on his part.

you don't attribute an event, rather you "relate" an event
This is incorrect. Is this case the causality of the flood could be either attributed or related to an angry god. I don't see how trivial fits in with the first part at all.
Trivial doesn't match.. totally agree.. but the second part does match..
Hope we don't get it anyway... My worest nightmare now is Chem.. There are lots of #s i am struggling with now, which I was not before. I think it's the stress kicking in..

Here is another one that was giving me problems.
Brackish: Water :: Rancid:_____
Answer key says butter but wouldnt milk make logical sense? Seeing that milk is a beverage like water, and I've never heard of "rancid butter" before, although I do acknowledge that butter can go rancid, albeit very slowly.

I chose milk as well when I stumbled upon that question.
I've heard of rancid butter more often than rancid milk. I think one typically refers to milk that's gone bad as spoiled, not rancid. 😕
Ha! Wikipedia to the rescue: http://en.wikipedia.org/wiki/Rancidification
I never realized rancid is a technical term. And butter does go bad; it creates butyric acid in the process, I believe.
"why do the elements sodium and chlorine bond so readily?"
i thought it was a relatively easy question and put the answer "electron sharing caused by low ionization energy for sodium and high electron affinity for chlorine"
but the answer says low ionization energy for sodium and low electron affinity for chlorine is the theoretically correct answer .. could someone explain how this could be. thanks!

This question is horrible^^ even given Collin's rationale for the two answers, none of the answers make sense. Because ionic bonds involve transfer of electrons. The truth is that chlorine has a very negative electron affinity, and sodium has a low ionization energy. But the answer choice "low and low" is coupled with the "sharing of electrons".
It is my understanding that both milk and butter can become rancid (or any comestible for that matter). Butter is derived from milk, hence is made of of the same constituents, so I do not understand how butter is a better choice when milk is a liquid, like water.
Because rancidification refers specifically to fats going bad and butter has a much higher fat composition (obviously; it's pretty much all fat) than milk.
It's not as though milk cannot become rancid, just that butter is the better choice for an answer in this situation.
I do find it funny that you choose to write the word comestible instead of something more obvious, like food...it makes me laugh for some reason. Not picking on you; I just find it interesting.
Agreed. Case closed!
Rancid - (of foods containing fat or oil) Smelling or tasting unpleasant as a result of being old and stale.
Milk technically could be right, but butter is a better answer.
EDIT - sorry didn't realized this was already answered
it's because the moon IS a type of satellite.
basically, a satellite is something that orbits something else, and the Earth's satellite is the moon. television is just an application of satellite technology; a television itself is not a type of satellite.
so since snow is a type of precipitate, the moon is a type of satellite
hope that helps!

Here's one that I ran into. Might help those taking the PCAT in September.
Calculus : Trigonometry :: Painting : ________
Collins states the answer as "palette," but this question was on one of the practice PCAT tests and the correct answer was "sculpture". The reasoning behind this is that calculus and trig are forms of math; painting and sculptures are forms of art.
