 Passage 2:Hornish moved to Penske's NASCAR program part-time in the Xfinity Series (then known as the Busch Series) during the 2006 season, and began driving part-time in the Sprint Cup Series (then known as the Nextel Cup Series) in 2007. He raced full-time in the Sprint Cup Series the following year, struggling at first, with eight top-ten finishes over his first three seasons and a top points placing of 28th (in 2009). Hornish returned part-time to the Xfinity Series (then known as the Nationwide Series) in 2011, winning one race. He drove full-time in the series the following year, finishing fourth in points. In 2012 Hornish replaced A. J. Allmendinger (suspended by NASCAR for failing a drug test) in Penske's No. 22 car midway through the season, earning one top-five finish.

 Passage 3:Indian swallowtails are found almost everywhere in the country. The Malabar banded peacock (Papilio buddha) and the Malabar banded swallowtail (Papilio liomedon) fly at sea level while the Apollos (Parnassius species), are to be found only in the highest alpine meadows of the Himalayas. Some species such as the common Mormon (Papilio polytes) and the blue Mormon (Papilio polymnestor) fly at ground level whereas others, such as the tailed jay (Graphium agamemnon) are normally found flying high in the forest canopy. The lime butterfly (Papilio demoleus) is a creature of arid scrub-land, occasionally being spotted even in the Thar Desert, while the tropical evergreen forests have their own representatives, such as the red Helen (Papilio helenus), the common bluebottle (Graphium cloanthus) and the Malabar raven (Papilio dravidarum). Indian papilionids such as the common Mormon (Papilio polytes) and great Mormon (Papilio memnon) show polymorphism with many mimetic female forms.
