Input: Consider Input: The Man Who Walked Between the Towers is a children's picture book written and illustrated by American Mordicai Gerstein. Published in 2003, the book recounts the heart-stopping achievement of Philippe Petit, a French man who, on an August morning in 1974, walked, lay, knelt and danced on a tightrope wire between the roofs of the twin towers of the World Trade Center, a quarter mile above the ground. Gerstein won the 2004 Caldecott Medal for his illustrations. The book has been adapted to film and ballet.

Output: what is the theme of the man who walked between the towers


Input: Consider Input: Patty Hill was a kindergarten principal in Louisville, Kentucky, developing various teaching methods at what is now the Little Loomhouse; her sister Mildred was a pianist and composer. The sisters used 'Good Morning to All' as a song that young children would find easy to sing. The combination of melody and lyrics in 'Happy Birthday to You' first appeared in print in 1912, and probably existed even earlier.

Output: who created the happy birthday song and when


Input: Consider Input: In a legislature, a special session (also extraordinary session) is a period when the body convenes outside of the normal legislative session. This most frequently occurs in order to complete unfinished tasks for the year (often delayed by conflict between political parties), such as outlining the government's budget for the next fiscal year, biennium, or other period. Special sessions may also be called during an economic downturn in order to cut the budget. In other cases, a special session may be convened to address special topics, or emergencies such as war or natural disaster.


Output: when would an emergency session of congress be held
