Problem: It is common to classify wood as either softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from dicotyledons (usually broad-leaved trees, e.g. oak) is called hardwood. These names are a bit misleading, as hardwoods are not necessarily hard, and softwoods are not necessarily soft. The well-known balsa (a hardwood) is actually softer than any commercial softwood. Conversely, some softwoods (e.g. yew) are harder than many hardwoods.
What's the scientific name for trees like the oak with broad leaves?
The answer is the following: dicotyledons

Problem: Forbes magazine began reporting on Beyonce's earnings in 2008, calculating that the $80 million earned between June 2007 to June 2008, for her music, tour, films and clothing line made her the world's best-paid music personality at the time, above Madonna and Celine Dion. They placed her fourth on the Celebrity 100 list in 2009 and ninth on the "Most Powerful Women in the World" list in 2010. The following year, Forbes placed her eighth on the "Best-Paid Celebrities Under 30" list, having earned $35 million in the past year for her clothing line and endorsement deals. In 2012, Forbes placed Beyonce at number 16 on the Celebrity 100 list, twelve places lower than three years ago yet still having earned $40 million in the past year for her album 4, clothing line and endorsement deals.

For the years 2009 to 2011, Beyonce earned an average of $70 million per year, and earned $40 million in 2012. In 2013, Beyonce's endorsements of Pepsi and H&M made her and Jay Z the world's first billion dollar couple in the music industry.
