The Topic/Main Idea/Subject
"Side" is the word in the sentence among the following choices given in the question that <span>should be replaced with domain specific language. The correct option among all the options that are given in the question is the second option. I hope that this is the answer that has actually come to your help.</span>
The struggle or clash would be the conflict(C) because conflict is a disagreement or a clash of ideas.
If I visited another nation and was only able to pack 3 items, I would have to choose carefully. The first thing I would pack is a dictionary or translation book of the new locations local language. This way I can make my way around and understand the basics of the language in order to live. The second thing I would bring is a pack of local treats / snacks in order to share with the new population. Being generous can help immensely in any new environment. The final thing I would bring it plenty of water, I have to drink if I want to survive.
The dictionary I would describe as a book of words to learn their language. The treats I would describe as food for them to enjoy. Finally, the water I would describe as nourishment for the soul.
I hope I've helped! :)
