A stained glass is a coloured glass. Specifically, a stained glass window refers to the windows with mosaics made from small pieces of coloured glass that can be found in many windows of churches and mosques. Some of them are especially precious and elaborate, showing biblical scenes and being true works of art.
Answer:
More student may have taken the test in the afternoon than in the morning.
Explanation:
Mrs. Orlof teaches two history classes, one in the morning and one in the afternoon. Yesterday she gave the same test to both classes. Anyone who failed the test must take a retest. Since a greater percentage of students who took the morning test failed the test than students who took the afternoon test, more of Orloff’s morning history students than afternoon history students will have to take the retest. The conclusion above is not necessarily valid because more student may have taken the test in the afternoon than in the morning.
