In intelligent mammals, such as primates, the cerebrum is larger relative to the rest of the brain. Intelligence itself is not easy to define, but indications of intelligence include the ability to learn, matched with behavioral flexibility. Rats, for example, are considered to be highly intelligent, as they can learn and perform new tasks, an ability that may be important when they first colonize a fresh habitat. In some mammals, food gathering appears to be related to intelligence: a deer feeding on plants has a brain smaller than a cat, which must think to outwit its prey.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What part of the brain is larger in rats compared to the rest of the brain?
Ah, so.. unanswerable

Melbourne is typical of Australian capital cities in that after the turn of the 20th century, it expanded with the underlying notion of a 'quarter acre home and garden' for every family, often referred to locally as the Australian Dream. This, coupled with the popularity of the private automobile after 1945, led to the auto-centric urban structure now present today in the middle and outer suburbs. Much of metropolitan Melbourne is accordingly characterised by low density sprawl, whilst its inner city areas feature predominantly medium-density, transit-oriented urban forms. The city centre, Docklands, St. Kilda Road and Southbank areas feature high-density forms.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Do the Docklands, St. Kilda Road, and Southbank areas feature high-density or low-density forms?
Ah, so.. high-density

Mexico City has numerous museums dedicated to art, including Mexican colonial, modern and contemporary art, and international art. The Museo Tamayo was opened in the mid-1980s to house the collection of international contemporary art donated by famed Mexican (born in the state of Oaxaca) painter Rufino Tamayo. The collection includes pieces by Picasso, Klee, Kandinsky, Warhol and many others, though most of the collection is stored while visiting exhibits are shown. The Museo de Arte Moderno (Museum of Modern Art) is a repository of Mexican artists from the 20th century, including Rivera, Orozco, Siqueiros, Kahlo, Gerzso, Carrington, Tamayo, among others, and also regularly hosts temporary exhibits of international modern art. In southern Mexico City, the Museo Carrillo Gil (Carrillo Gil Museum) showcases avant-garde artists, as does the University Museum/Contemporary Art (Museo Universitario Arte Contemporáneo – or MUAC), designed by famed Mexican architect Teodoro González de León, inaugurated in late 2008.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who's art collection was the reason the Museo Tamayo opened?
Ah, so..
Rufino Tamayo
