D. Farmers who resisted collective farming were sent to forced labor camps.
Explanation:
Stalin promoted " Collectivization." as the official Soviet policy for the countryside and this started in 1929, transforming the traditional lifestyle of peasants and agriculture.
<em>A major change was the removal of the kulaks or independent and wealthy peasants. </em>
The people were mean to form households that worked in common "collective farms called kolkhozes". By 1933 the system was well established along with the USSR republics and the failure of the policy was mostly suffered in the next decade: <em>a series of shortages of elementary and essential grains caused production levels to fall, and they were secretly being hidden to the nation and the rest of the world.</em>
The increase of technology used during the construction of the railroads and factories is considered the second Industrial Revolution. This is because of the many inventions and help of transportation use. Hope this helps.
