Here is a question about this article: The Paris Region economy has gradually shifted from industry to high-value-added service industries (finance, IT services, etc.) and high-tech manufacturing (electronics, optics, aerospace, etc.). The Paris region's most intense economic activity through the central Hauts-de-Seine department and suburban La Defense business district places Paris' economic centre to the west of the city, in a triangle between the Opera Garnier, La Defense and the Val de Seine. While the Paris economy is dominated by services, and employment in manufacturing sector has declined sharply, the region remains an important manufacturing centre, particularly for aeronautics, automobiles, and "eco" industries.
What is the answer to this question: Where is Paris economic Centre located?

So... west of the city, in a triangle between the Opera Garnier, La Defense and the Val de Seine

Here is a question about this article: Further problems hampered the Arctic project after the commencement of drilling in 2012, as Shell dealt with a series of issues that involved air permits, Coast Guard certification of a marine vessel and severe damage to essential oil-spill equipment. Additionally, difficult weather conditions resulted in the delay of drilling during mid-2012 and the already dire situation was exacerbated by the "Kulluk" incident at the end of the year. Royal Dutch Shell had invested nearly US$5 billion by this stage of the project.
What is the answer to this question: What conditions caused the delay of drilling in mid-2012?

So... difficult weather

Here is a question about this article: In presidential elections, Montana was long classified as a swing state, though the state has voted for the Republican candidate in all but two elections from 1952 to the present. The state last supported a Democrat for president in 1992, when Bill Clinton won a plurality victory. Overall, since 1889 the state has voted for Democratic governors 60 percent of the time and Democratic presidents 40 percent of the time, with these numbers being 40/60 for Republican candidates. In the 2008 presidential election, Montana was considered a swing state and was ultimately won by Republican John McCain, albeit by a narrow margin of two percent.
What is the answer to this question: How often does Montana voted for a Democratic president?

40 percent
