Playing eighteenth-century music on the instruments of that period provides valuable information about how the music originally sounded. Eighteenth-century instruments cannot be played without being restored, however,and restoring such an instrument destroys all of the information that researchers could obtain from it about eighteenth-century instrument-making techniques.
If the statements above are true, which of the following must be true on the basis of them?
(A) Eighteenth-century instruments cannot be used to provide information about the original techniques used in playing such instruments if they have been restored.
(B) Eighteenth-century instruments that have been restored can provide information only about how eighteenth-century music originally sounded
(C) Eighteenth-century instruments are the only source of information about the instrument-making techniques of that period.
(D) An eighteenth-century instrument that has not been restored can provide more information than can one that has been restored.
(E) An eighteenth-century instrument cannot serve as a source of new information about eighteenth-century instrument-making techniques once it can be played

INFERENCE: Must be true based on the stem.
Playing 18c music on the instruments of the 18c provides info about how the music originally sound.
But, 18c instruments cannot be played wo being restored = destroyg all info rsrch could obtain about 18c instrument-making technique.
Playing 18c music on 18c instruments (but they cannot be used wo restoring them, which destroys their instrument-making tech; but, it can still play 18c music..) = original music.
a) 18c instrument cannot provide info about techs used in playing; false “18c instruments cannot provide info about instrument-making technique”, the stem doesn’t say anything about music playing techniques from restored or not restored instruments.
b) 18c instruments restored can provide info about 18c music; nope.. 18c instruments restored can provide info about 18c music when they are played..
c) 18c instruments are the only source of info about instrument-making techniques of 18c; false.. stem never said its the only source.
d) 18c instrument not restored can provide more info than 18c instrument restored; maybe..
e) 18c instrument played cannot be a source of new info about 18c instrument-making techniques; true: since they can only be played if they are restored, which destroys all inst-making techniques.
(E) I think?
