<span>The correct answer is A.
Gregorian chant is monophonic which means that it has a basic texture. It
consists only of melody and is not accompanied by a harmony. The same note is
produced from men and women and all notes are sung together. The Gregorian
chant is commonly used in churches and other religious congregations and was
first developed in 9th and 10th century in western and
central Europe. Pope St. Gregory the Great is credited for the chant.</span>

I think a good addition to a collection of writing instruments that were unique to the twentieth century would be pens and pencils like we have now because back then they dipped feathers in ink and then wrote with them. They were very special because people wrote there feeling and grocery list and drew thing as art. And maybe more to add on would be paint brushes to make beautiful art like they did back then. I hope this helped u and that all your questions are answered.
