Hi @sprozes,

Thanks for the question! Take a look at the third paragraph starting at line 32. The passage here describes a process in which more fish is required as an input than fish is produced as an output, and the author of the passage clearly views this as a problem. This is what (C) is telling us: that processes that make food should put out more food then they need taking in. (E), on the other hand, is too strong because of the “only if” condition. There could very reasonably be reasons to implement food processes that don’t involve replacing other processes with undesirable ecological effects. A brief diagram of the contrapositive of this statement might help illustrate the force of this logic:

~Replace other methods that have undesirable ecological effects —> ~Should employ new methods of food production

which is too strong a statement.

Hope this helps! Feel free to ask any other questions that you might have.
