I'm confused about how to use the 'that' demonstrative in the following sentence:
Finally, in Part 4 we analysed the results that obtained in the parts mentioned above, and we showed further experiments we have done to contribute to the topics of those parts.
In the first bold clause, I used
results is defined in the context before. And in the second bold clause, I didn't use
that after the word
further experiments were not defined.
Is this correct?
