Problem: Botany:

Increasing knowledge of plant anatomy, morphology and life cycles led to the realisation that there were more natural affinities between plants than the artificial sexual system of Linnaeus had indicated. Adanson (1763), de Jussieu (1789), and Candolle (1819) all proposed various alternative natural systems of classification that grouped plants using a wider range of shared characters and were widely followed. The Candollean system reflected his ideas of the progression of morphological complexity and the later classification by Bentham and Hooker, which was influential until the mid-19th century, was influenced by Candolle's approach. Darwin's publication of the Origin of Species in 1859 and his concept of common descent required modifications to the Candollean system to reflect evolutionary relationships as distinct from mere morphological similarity.

What led scientists to believe that plants should be classified according to something other than just sexual system?
---
A: Increasing knowledge of plant anatomy


Problem: Dominican Order:

Doctrinal development has had an important place in the restoration of the Preachers. Several institutions, besides those already mentioned, played important parts. Such is the Biblical school at Jerusalem, open to the religious of the order and to secular clerics, which publishes the Revue Biblique. The faculty of theology at the University of Fribourg, confided to the care of the Dominicans in 1890, is flourishing, and has about 250 students. The Pontificium Collegium Internationale Angelicum, the future Pontifical University of Saint Thomas Aquinas, Angelicum established at Rome in 1908 by Master Hyacinth Cormier, opened its doors to regulars and seculars for the study of the sacred sciences. In addition to the reviews above are the Revue Thomiste, founded by Père Thomas Coconnier (d. 1908), and the Analecta Ordinis Prædicatorum (1893). Among numerous writers of the order in this period are: Cardinals Thomas Zigliara (d. 1893) and Zephirin González (d. 1894), two esteemed philosophers; Alberto Guillelmotti (d. 1893), historian of the Pontifical Navy, and Heinrich Denifle, one of the most famous writers on medieval history (d. 1905).[citation needed]

Problem: Portugal:

The country continued to be governed by a Junta de Salvação Nacional until the Portuguese legislative election of 1976. It was won by the Portuguese Socialist Party (PS) and Mário Soares, its leader, became Prime Minister of the 1st Constitutional Government on 23 July. Mário Soares would be Prime Minister from 1976 to 1978 and again from 1983 to 1985. In this capacity Soares tried to resume the economic growth and development record that had been achieved before the Carnation Revolution, during the last decade of the previous regime. He initiated the process of accession to the European Economic Community (EEC) by starting accession negotiations as early as 1977.
