Problem: Flowering plant:

The earliest known macrofossil confidently identified as an angiosperm, Archaefructus liaoningensis, is dated to about 125 million years BP (the Cretaceous period), whereas pollen considered to be of angiosperm origin takes the fossil record back to about 130 million years BP. However, one study has suggested that the early-middle Jurassic plant Schmeissneria, traditionally considered a type of ginkgo, may be the earliest known angiosperm, or at least a close relative. In addition, circumstantial chemical evidence has been found for the existence of angiosperms as early as 250 million years ago. Oleanane, a secondary metabolite produced by many flowering plants, has been found in Permian deposits of that age together with fossils of gigantopterids. Gigantopterids are a group of extinct seed plants that share many morphological traits with flowering plants, although they are not known to have been flowering plants themselves.

What evidence has shown that flowering plants existed 125 million years BP?

Problem: Pub:

The most popular term in English-speaking Canada used for a drinking establishment was "tavern", until the 1970s when the term "bar" became widespread as in the United States. In the 1800s the term used was "public house" as in England but "pub culture" did not spread to Canada. A fake "English looking" pub trend started in the 1990s, built into existing storefronts, like regular bars. Most universities in Canada have campus pubs which are central to student life, as it would be bad form just to serve alcohol to students without providing some type of basic food. Often these pubs are run by the student's union. The gastropub concept has caught on, as traditional British influences are to be found in many Canadian dishes. There are now pubs in the large cities of Canada that cater to anyone interested in a "pub" type drinking environment.[citation needed]

In what decade could one find an "English looking" pub trend in Canada?

A: 1990s

Problem: Avicenna:

Liber Aboali Abincine de Anima in arte Alchemiae was the most influential, having influenced later medieval chemists and alchemists such as Vincent of Beauvais. However Anawati argues (following Ruska) that the de Anima is a fake by a Spanish author. Similarly the Declaratio is believed not to be actually by Avicenna. The third work (The Book of Minerals) is agreed to be Avicenna's writing, adapted from the Kitab al-Shifa (Book of the Remedy). Ibn Sina classified minerals into stones, fusible substances, sulfurs, and salts, building on the ideas of Aristotle and Jabir. The epistola de Re recta is somewhat less sceptical of alchemy; Anawati argues that it is by Avicenna, but written earlier in his career when he had not yet firmly decided that transmutation was impossible.

What is the kitab al-Shifa?

A: Book of the Remedy

Problem: Samoa:

Some Samoans are spiritual and religious, and have subtly adapted the dominant religion of Christianity to 'fit in' with fa'a Samoa and vice versa. As such, ancient beliefs continue to co-exist side-by-side with Christianity, particularly in regard to the traditional customs and rituals of fa'a Samoa. The Samoan culture is centred around the principle of vafealoa'i, the relationships between people. These relationships are based on respect, or fa'aaloalo. When Christianity was introduced in Samoa, most Samoan people converted. Currently 98% of the population identify themselves as Christian.

What happened when fa'a Samoa was introduced?
