The discovery of penicillin was one of the great breakthroughs of modern science. Alexander Fleming, the Scottish scientist, noticed that
certain types of bacteria were killed when exposed to mold. Repeated tests confirmed that this mold (from which penicillin is derived) did indeed
check the growth of many microbes. Since its discovery over 50 years ago, penicillin has been used to treat a variety of diseases and infections.
During World War II, battlefield wounds were treated with penicillin, and thousands of lives were saved. Today, penicillin
is still used in the
treatment of many diseases.
Which happened first?
1. Penicillin saved many lives in World War II.
02. Tests confirmed that penicillin kills microbes.
3. Many diseases were treated with penicillin
4. Fleming did research using mold.

read this excerpt from “incidents in the life of a slave girl.”

i went about my evening work with trembling steps. mr. flint twice called from his chamber door to inquire why the house was not locked up. i replied that i had not done my work. "you have had time enough to do it," said he. "take care how you answer me! "

i shut all the windows, locked all the doors, and went up to the third story, to wait till midnight. how long those hours seemed, and how fervently i prayed that god would not forsake me in this hour of utmost need! i was about to risk everything on the throw of a die; and if i failed, o what would become of me and my poor children? they would be made to suffer for my fault.

at half past twelve i stole softly down stairs. i stopped on the second floor, thinking i heard a noise. i felt my way down into the parlor, and looked out of the window. the night was so intensely dark that i could see nothing. i raised the window very softly and jumped out. large drops of rain were falling, and the darkness bewildered me. i dropped on my knees, and breathed a short prayer to god for guidance and protection. i groped my way to the road, and rushed towards the town with almost lightning speed.
