Sorry, I did not mean to say in wrong way. Trust me. I was just wondering if there could be another obvious way to look at the given info.
Anyway.
In case of inferrence questions, always go for a option which tells you the 'meat' of the given info. I hope you get what I meant to say. So considering this, the given argument tells us that, the good meal is equally dependent on good natural sources (food -> soil ) as well as cultural sources (such as farming techniques).
Now,
A. The creation of good meals depends on both natural and cultural conditions. - Correct
B. Natural resources cannot be maintained properly without good farming practices. - Given info did not say this.
C. Good soil is a prerequisite of good farming. - One of the permises
D. Any society with good cultural values will have a good cuisine. - not necessary, need good natural sources as well
E. When food is bad, its because of poor soil and ultimately, bad farming practices - Given info did not say this.
[Always avoid options that are too extreme, make un-necessary assumptions, use information other than given]
