题目内容：
根据下列材料，回答题Technology has been an encouragement of historical change．It acted as such a force in Eng.land beginning in the eighteenth century，and across the entire Western Worid in me nineteenth．
Rapld advances were made in the use of scientific findings in the manufacture(制造)of goods,which has changed ideas about work．One of the first changes was that other formsof energy have taken the place of human power．Along with this calIle the increased use of Inachines to manufac ture products in less time．
People also developed machines that could produce the salTle parts for a product：each nail was exactly like every other nail，meaning that each nail could be changed for every other nail．This means that goods could be mass produced，though mass production required breaking Droduction down into smaller and smaller tasks．
Once this was done，workers no longer started on the product and labored to complete it．Instead，they might work only one thousandth of it，other workers completing their own parts in certain order.There is nothing strange about this manufacturing work by today’s standards．Highlv skilled workers were unable to compare with the new production techniques，as mass production allowed goods of high standard to be produced in greater number than could ever be done bv hand．But the skilled worker wasn’t the only loser，the common workers lost t00．SilIlilar chaIlges forced farmers away．The increased mechanization(机械化)of agriculture freed masses of workers from ploughing the land and harvesting its crops．They had little choice but to stream toward the rapidlv developing industrial centers．Increasingly，standards were set by machines．Workers no 1onger owned their own tools，their skill was no longer valued，and pride in their work was n0 10nger possible．Workers fed，looked after and repaired the machines that could work faster tllan humansat greatly reduced cost．
In this passage，which of the following is NOT considered as a change caused bv the use of scientific findings in the production of goods? A．Other forms of energy have taken the place of human power．
B．The increased exploitation of workers in the l9th centllry．
C．The increased use of machines to make products in less time
D．The use of machines producing parts of the same standard．
