Answer:
The death of Dr. Martin Luther Kind Jr negatively impacted the effort to expand civil rights for African Americans. Yes, his legacy was carried out no matter what and his footprint for African-American rights still stands but his presence was definitely missed as it could have influenced many more marches and events not just for the African-American community but also for other campaigns such as the "Poor-People's Campaign". He would also had continued to speak against the US involvement in the Vietnam war, and probably against many more conflicts in the future.
Letter A is the correct answer.
When speaking of conflict, people's genders or ethnic background are not as powerful determinants of a person's conflict style as the situation at hand and the behaviors of the ones involved. In order for them to have a constructive conflict, it's necessary to identify the problem (or unmet needs), make a date, describe the problem/need, consider the other person's point of view, try to negoatiate a solution, and follow-up the solution.
