Context and question: Stems mainly provide support to the leaves and reproductive structures, but can store water in succulent plants such as cacti, food as in potato tubers, or reproduce vegetatively as in the stolons of strawberry plants or in the process of layering. Leaves gather sunlight and carry out photosynthesis. Large, flat, flexible, green leaves are called foliage leaves. Gymnosperms, such as conifers, cycads, Ginkgo, and gnetophytes are seed-producing plants with open seeds. Angiosperms are seed-producing plants that produce flowers and have enclosed seeds. Woody plants, such as azaleas and oaks, undergo a secondary growth phase resulting in two additional types of tissues: wood (secondary xylem) and bark (secondary phloem and cork). All gymnosperms and many angiosperms are woody plants. Some plants reproduce sexually, some asexually, and some via both means.
What are the stems used for in cacti?
Answer: store water
Context and question: In the aftermath of the 1986 U.S. attack, the army was purged of perceived disloyal elements, and in 1988, Gaddafi announced the creation of a popular militia to replace the army and police. In 1987, Libya began production of mustard gas at a facility in Rabta, although publicly denying it was stockpiling chemical weapons, and unsuccessfully attempted to develop nuclear weapons. The period also saw a growth in domestic Islamist opposition, formulated into groups like the Muslim Brotherhood and the Libyan Islamic Fighting Group. A number of assassination attempts against Gaddafi were foiled, and in turn, 1989 saw the security forces raid mosques believed to be centres of counter-revolutionary preaching. In October 1993, elements of the increasingly marginalised army initiated a failed coup in Misrata, while in September 1995, Islamists launched an insurgency in Benghazi, and in July 1996 an anti-Gaddafist football riot broke out in Tripoli. The Revolutionary Committees experienced a resurgence to combat these Islamists.
Where did Libya manufacture mustard gas?
Answer: Rabta
Context and question: Immanuel Kant (17241804) tried to reconcile rationalism and religious belief, individual freedom and political authority, as well as map out a view of the public sphere through private and public reason. Kant's work continued to shape German thought, and indeed all of European philosophy, well into the 20th century. Mary Wollstonecraft was one of England's earliest feminist philosophers. She argued for a society based on reason, and that women, as well as men, should be treated as rational beings. She is best known for her work A Vindication of the Rights of Woman (1791).
In what year was A Vindication on the Rights of Woman published?
Answer:
1791
