I just had one about The Ancient Tablet. A tablet with strange markings was found and my choices were:
-focus research on tablet
or
-put it on display
Chose: focus research on the tablet.
Result: Got a higher level of alchemy but at the expense of 1000 tech points. (I only had level 2 alchemy at the time so it worked out great for me but I don't know if the result might be different if alchemy is already fully researched.)
