Problem: Species boundaries in plants may be weaker than in animals, and cross species hybrids are often possible. A familiar example is peppermint, Mentha piperita, a sterile hybrid between Mentha aquatica and spearmint, Mentha spicata. The many cultivated varieties of wheat are the result of multiple inter- and intra-specific crosses between wild species and their hybrids. Angiosperms with monoecious flowers often have self-incompatibility mechanisms that operate between the pollen and stigma so that the pollen either fails to reach the stigma or fails to germinate and produce male gametes. This is one of several methods used by plants to promote outcrossing. In many land plants the male and female gametes are produced by separate individuals. These species are said to be dioecious when referring to vascular plant sporophytes and dioicous when referring to bryophyte gametophytes.
How do some plants avoid cross pollination?
The answer is the following: pollen either fails to reach the stigma

Problem: Drama is literature intended for performance. The form is often combined with music and dance, as in opera and musical theatre. A play is a subset of this form, referring to the written dramatic work of a playwright that is intended for performance in a theatre; it comprises chiefly dialogue between characters, and usually aims at dramatic or theatrical performance rather than at reading. A closet drama, by contrast, refers to a play written to be read rather than to be performed; hence, it is intended that the meaning of such a work can be realized fully on the page. Nearly all drama took verse form until comparatively recently.
Literature intended for performance is what?
The answer is the following: Drama

Problem: Article 10 of the Berne Convention mandates that national laws provide for limitations to copyright, so that copyright protection does not extend to certain kinds of uses that fall under what the treaty calls "fair practice," including but not limited to minimal quotations used in journalism and education. The laws implementing these limitations and exceptions for uses that would otherwise be infringing broadly fall into the categories of either fair use or fair dealing. In common law systems, these fair practice statutes typically enshrine principles underlying many earlier judicial precedents, and are considered essential to freedom of speech.
What do these statutes represent?
The answer is the following: principles underlying many earlier judicial precedents

Problem: The Reed Dance today is not an ancient ceremony but a development of the old "umchwasho" custom. In "umchwasho", all young girls were placed in a female age-regiment. If any girl became pregnant outside of marriage, her family paid a fine of one cow to the local chief. After a number of years, when the girls had reached a marriageable age, they would perform labour service for the Queen Mother, ending with dancing and feasting. The country was under the chastity rite of "umchwasho" until 19 August 2005.
Who became bound by umchwaso in Swaziland?
The answer is the following:
all young girls
