''Single-family farms are making higher profits'' and ''mechanized farms require a larger labor force than traditional farms'' are the two statements that are not true about the modern day agriculture.
Single-family farms are not making higher profits, thy are in fact making much less profit, and especially in the developed countries this type of farms are systematically brought to minimum and are on the verge to stop existing.
Mechanized farms do not require larger labor force, totally opposite, they require much less labor force. The whole point of the mechanization is to lower the requirements for labor force and increase the speed and efficiency of the work, so this made it possible that much fewer people to be able to do much more work with the help of the mechanization.
It is important to keep in perspective what modern agriculture has achieved. More efficient crops, seeding techniques, care-taking techniques as well as genetically modified food are some of its accomplishments. Under this light, 1 is true thanks to modern agriculture; crops have multiplied their efficiency after the introduction of these innovations. Also, due to the increased productivity, we need to cultivate less land to achieve the same yield and this is again thanks to modernity. However,mechanized farms, a product of modern agriculture require less labor to be run, not more and as far as statement 2 is regarded, big corporations make much more profit than a small single-family farm. Hence, the correct answer is II and IV
