Problem: Please answer a question about the following article about Royal Dutch Shell:
Shell's primary business is the management of a vertically integrated oil company. The development of technical and commercial expertise in all stages of this vertical integration, from the initial search for oil (exploration) through its harvesting (production), transportation, refining and finally trading and marketing established the core competencies on which the company was founded. Similar competencies were required for natural gas, which has become one of the most important businesses in which Shell is involved, and which contributes a significant proportion of the company's profits. While the vertically integrated business model provided significant economies of scale and barriers to entry, each business now seeks to be a self-supporting unit without subsidies from other parts of the company.
Each business now seeks to become what type of unit?
A: self-supporting


Question: Read this and answer the question

Before the Hellenistic period, Greek colonies had been established on the coast of the Crimean and Taman peninsulas. The Bosporan Kingdom was a multi-ethnic kingdom of Greek city states and local tribal peoples such as the Maeotians, Thracians, Crimean Scythians and Cimmerians under the Spartocid dynasty (438–110 BCE). The Spartocids were a hellenized Thracian family from Panticapaeum. The Bosporans had long lasting trade contacts with the Scythian peoples of the Pontic-Caspian steppe, and Hellenistic influence can be seen in the Scythian settlements of the Crimea, such as in the Scythian Neapolis. Scythian pressure on the Bosporan kingdom under Paerisades V led to its eventual vassalage under the Pontic king Mithradates VI for protection, circa 107 BCE. It later became a Roman client state. Other Scythians on the steppes of Central Asia came into contact with Hellenistic culture through the Greeks of Bactria. Many Scythian elites purchased Greek products and some Scythian art shows Greek influences. At least some Scythians seem to have become Hellenized, because we know of conflicts between the elites of the Scythian kingdom over the adoption of Greek ways. These Hellenized Scythians were known as the "young Scythians". The peoples around Pontic Olbia, known as the Callipidae, were intermixed and Hellenized Greco-Scythians.

From whom did the Scythians of Central Asia discover Hellenistic culture?
Answer: Greeks of Bactria

Proponents of affirmative action argue that by nature the system is not only race based, but also class and gender based. To eliminate two of its key components would undermine the purpose of the entire system. The African American Policy Forum believes that the class based argument is based on the idea that non-poor minorities do not experience racial and gender based discrimination. The AAPF believes that "Race-conscious affirmative action remains necessary to address race-based obstacles that block the path to success of countless people of color of all classes". The groups goes on to say that affirmative action is responsible for creating the African American middle class, so it does not make sense to say that the system only benefits the middle and upper classes.
Other than being race and gender based, what did believers in affirmative action also feel that the system discriminated against?
class


Input: Josip Broz Tito
During his life and especially in the first year after his death, several places were named after Tito. Several of these places have since returned to their original names, such as Podgorica, formerly Titograd (though Podgorica's international airport is still identified by the code TGD), and Užice, formerly Titovo Užice, which reverted to its original name in 1992. Streets in Belgrade, the capital, have all reverted to their original pre–World War II and pre-communist names as well. In 2004, Antun Augustinčić's statue of Broz in his birthplace of Kumrovec was decapitated in an explosion. It was subsequently repaired. Twice in 2008, protests took place in Zagreb's Marshal Tito Square, organized by a group called Circle for the Square (Krug za Trg), with an aim to force the city government to rename it to its previous name, while a counter-protest by Citizens' Initiative Against Ustašism (Građanska inicijativa protiv ustaštva) accused the "Circle for the Square" of historical revisionism and neo-fascism. Croatian president Stjepan Mesić criticized the demonstration to change the name. In the Croatian coastal city of Opatija the main street (also its longest street) still bears the name of Marshal Tito, as do streets in numerous towns in Serbia, mostly in the country's north. One of the main streets in downtown Sarajevo is called Marshal Tito Street, and Tito's statue in a park in front of the university campus (ex. JNA barrack "Maršal Tito") in Marijin Dvor is a place where Bosnians and Sarajevans still today commemorate and pay tribute to Tito (image on the right). The largest Tito monument in the world, about 10 m (33 ft) high, is located at Tito Square (Slovene: Titov trg), the central square in Velenje, Slovenia. One of the main bridges in Slovenia's second largest city of Maribor is Tito Bridge (Titov most). The central square in Koper, the largest Slovenian port city, is as well named Tito Square.

When did Uziece revert to its original name?
Output: 1992


Problem: Please answer a question about the following article about Flowering plant:
Flower evolution continues to the present day; modern flowers have been so profoundly influenced by humans that some of them cannot be pollinated in nature. Many modern domesticated flower species were formerly simple weeds, which sprouted only when the ground was disturbed. Some of them tended to grow with human crops, perhaps already having symbiotic companion plant relationships with them, and the prettiest did not get plucked because of their beauty, developing a dependence upon and special adaptation to human affection.
How long has flower evolution occurred? 
A:
present day
