  Question 42:

• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

  During the 19th century, women in the U. S organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and most importantly to free slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Phillips also supported the rights of women to speak and participate equally with men in anti-slavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in order to better their living conditions and the conditions of others. When the Civil war ended in 1865, the 14th, and 15th, Amendments to the Constitution adopted in 1868 and 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded to demands by feminists, but eastern states resisted more stubbornly than ever before. A woman's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, when the 19th Amendment granted women the right to vote.

  Question: What does the 19th Amendment guarantee?
