To find the second intermediate conclusion, we need to combine the first two premises. We can do this by using the method of immediate inference by conversion: "No T are N" can be converted to "No N are T". Now we can see that there is a sub-contrary relationship between "All F are G" and "No N are T", which allows for the possibility of some F not being T. Moreover, the third premise tells us that "Some K are N", which means that there exists at least one thing that is both K and N. Therefore, it follows that "Some K are not F" (since we have already established that some F may not be T). Therefore, the correct answer is C.
