A scoring rubric is an attempt to communicate expectations of quality around a task. In many cases, scoring rubrics are used to delineate consistent criteria for grading. Because the criteria are public, a scoring rubric allows teachers and students alike to evaluate criteria, which can be complex and subjective.
        
                    
             
        
        
        
Explanation:
The Abbasid caliphs established the city of Baghdad in 762 CE. It became a center of learning and the hub of what is known as the Golden Age of Islam.
The Islamic Golden Age refers to a period in the history of Islam, traditionally dated from the 8th century to the 13th century, during which much of the historically Islamic world was ruled by various caliphates and science, economic development, and cultural works flourished. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786–809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the world’s classical knowledge into the Arabic language.

Despite popular belief, the U.S. Constitution does not provide for the popular election of the American president. It provides for popular election of presidential electors. Each candidate who qualifies for a given state's ballot must designate certain individuals who will serve as his or her electors if that candidate wins the popular vote in that state.
When each state certifies a winner of its overall popular vote, that winner is entitled to send all his or her electors to that state's Capitol, where they will officially record their votes for their candidate. All the electors in all the states do it on the same day, the first Monday after the second Wednesday of December. This year it is Dec. 19, which is the latest it can be, just as this year's Election Day is the latest it can be.
