Yes, your answers are correct. Please try to put b and c into your own words.

a. When Lincoln referred to "four score and seven years ago," he was talking about 87 years ago. To determine the year, you can calculate four score (4 times 20) plus seven years ago from the current year.

Example:
1. Determine the current year.
Let's assume the current year is 2023.

2. Calculate four score and seven years ago.
Four score is 4 times 20, which is equal to 80. Adding 80 to 7 gives us 87.

3. Subtract 87 from the current year.
2023 - 87 = 1936

Therefore, Lincoln was referring to the year 1936.

b. Lincoln said that the Civil War was testing whether our nation can long endure. A simpler way to put this is that the Civil War was testing the endurance or the ability of our nation to survive.

c. According to Lincoln, his purpose in coming to Gettysburg was to dedicate a portion of the battlefield as a final resting place for those who gave their lives. A simpler way to put this is that Lincoln came to Gettysburg to set aside a part of the battlefield as a place of remembrance for those who died.

d. According to Lincoln, Union soldiers who died at Gettysburg should be remembered by dedicating a portion of the field to them.
