How does geography effect the ability to adapt and refine inventions for use?This can be found in Chapter 13

I believe that what you are talking about is Diamond's
discussion of two ways in which geography affects the likelihood of adaptation and use
of technology.

First, he argues that societies can adapt
technologies if they are geographically lucky.  In other words, if your society is near
to one that innovates, you can easily adapt the innovation for your own use.  This has
nothing to do with your society's values and everything to do with its
location.

Second, he argues that isolated societies do not
really need technology.  He argues that Japan could stop using firearms because there
was no neighboring country that could invade it and conquer it.  If it had been next
door to another country, it would have had to keep using firearms to avoid being
conquered.

So if you are near to other countries that have
technology, you are able to get that technology and you are pretty much forced to get
and use it as well.
