Since the Spanish transition to democracy (1975–1982), Catalan has been institutionalizated as an official language, language of education, and language of mass media; all of which have contributed to its increased prestige. In Catalonia, there is no parallel of a large, bilingual, European, non-state speech community. The teaching of Catalan is mandatory in all schools, but it is possible to use Spanish for studying in the public education system of Catalonia in two situations, if the teacher assigned to a class chooses to use Spanish, or during the learning process of one or some recently arrived students.  There is also some intergenerational shift towards Catalan.
Since the transition, what is the official language?
Catalan

Bird migration is not limited to birds that can fly. Most species of penguin (Spheniscidae) migrate by swimming. These routes can cover over 1,000 km (620 mi). Dusky grouse Dendragapus obscurus perform altitudinal migration mostly by walking. Emus Dromaius novaehollandiae in Australia have been observed to undertake long-distance movements on foot during droughts.
Where are Emus from?
Australia

On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.
What doctor originally turned Donda West down for her plastic surgery operation?
Andre Aboolian
