Let's carefully examine the given data to determine who opposed the Civil Rights Act of 1964.
The table displays the following:
- Republican votes: 27 Yes, 6 No
- Democrat votes: 46 Yes, 21 No
- Northern States votes: 72 Yes, 6 No
- Southern States votes: 1 Yes, 21 No
By summing up these values, we calculate the total number of votes in each group:
- Total Republican votes: 27 Yes + 6 No = 33
- Total Democrat votes: 46 Yes + 21 No = 67
- Total Northern States votes: 72 Yes + 6 No = 78
- Total Southern States votes: 1 Yes + 21 No = 22
Now let's determine the proportions of opposition (No votes) within each group:
- Proportion of Republican opposition: 6 No / 33 Total = 0.1818 (approximately 18.18%)
- Proportion of Democrat opposition: 21 No / 67 Total = 0.3134 (approximately 31.34%)
- Proportion of Northern States opposition: 6 No / 78 Total = 0.0769 (approximately 7.69%)
- Proportion of Southern States opposition: 21 No / 22 Total = 0.9545 (approximately 95.45%)
From these values, it's clear that the group with the highest proportion of opposition (No votes) is the residents of Southern States, with approximately 95.45% opposing the Civil Rights Act of 1964.
Thus, the significant opposition came from the residents of Southern States. Therefore, the correct answer is:
Residents of Southern States.
This analysis allows us to conclude that the strongest opposition was from Southern States, as evidenced by the high percentage of No votes.
