<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>
The first one can be seen either way. For me, I saw a vase first. In all of the pictures, the black drawing is considered the positive space and the white background behind it is considered to be the negative space. If you look at the vase picture again and imagine the background to be the black portion, you see two faces.
