Input: Article: In 2012, Madonna performed at Super Bowl XLVI halftime show, visualized by Cirque Du Soleil and Jamie King and featured special guests LMFAO, Nicki Minaj, M.I.A. and Cee Lo Green. It became the then most-watched Super Bowl halftime show in history with 114 million viewers, higher than the game itself. It was also revealed that the singer had signed a three-album deal with Interscope Records, who would act as the distributor in partnership with her 360 deal with Live Nation. Her twelfth studio album, MDNA, was released in March 2012 and saw collaboration with various producers, most notably with William Orbit again and Martin Solveig. The album was well received by music critics, with Priya Elan from NME calling it "a ridiculously enjoyable romp", citing its "psychotic, soul-bearing stuff" as "some of the most visceral stuff she's ever done." MDNA debuted at number one on the Billboard 200 and many other countries worldwide. Madonna surpassed Elvis Presley's record for the most number-one album by a solo artist in the UK. The lead single "Give Me All Your Luvin'", featuring guest vocals from Minaj and M.I.A., became Madonna's record-extending 38th top-ten hit on the Billboard Hot 100.

Now answer this question: When was MDNA released?

Output: March 2012

Input: Article: In philosophy, emotions are studied in sub-fields such as ethics, the philosophy of art (for example, sensory–emotional values, and matters of taste and sentimentality), and the philosophy of music (see also Music and emotion). In history, scholars examine documents and other sources to interpret and analyze past activities; speculation on the emotional state of the authors of historical documents is one of the tools of interpretation. In literature and film-making, the expression of emotion is the cornerstone of genres such as drama, melodrama, and romance. In communication studies, scholars study the role that emotion plays in the dissemination of ideas and messages. Emotion is also studied in non-human animals in ethology, a branch of zoology which focuses on the scientific study of animal behavior. Ethology is a combination of laboratory and field science, with strong ties to ecology and evolution. Ethologists often study one type of behavior (for example, aggression) in a number of unrelated animals.

Now answer this question: Along with laboratory work, what does an ethologist engage in?

Output: field science
