instruction:
In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
question:
passage: where (A) and (B) express the concentration of the species A and B (usually in moles per liter (molarity, M)). The exponents x and y are the partial orders of reaction for A and B and the overall reaction order is the sum of the exponents. These are often positive integers, but they may also be zero, fractional, or negative. The constant k is the reaction rate constant or rate coefficient of the reaction and has units of 1/time. Its value may depend on conditions such as temperature, ionic strength, surface area of an adsorbent, or light irradiation.
 question: is it possible to have a negative order of reaction?
answer:
Yes


question:
passage: There is a great deal of debate as to where the boundaries lie between fact and fiction in the book. Roberts has stated the characters in the story are largely invented, and that he merged different elements taken from true events and people into such events and characters like Prabaker 'of the big smile'. Prabhakar Kisan Khare was a real-life individual, as are the members of Khare family from the book (Kisan, Rukhma, Kishor and Parvati Khare) whose names appear on government issued identity cards. The family resides in the Navy Nagar slum where the lead character Shantaram also lived. The Khare family disputes many of Roberts' claims, although they acknowledge close association with Gregory Roberts in the 1980s. Prabhakar died in an accident in 1988 in circumstances matching the event in the book. In March 2006, the Mumbai Mirror reported they may have discovered the inspiration for the big smile of the character Prabhakar as belonging to a still living cab driver called Kishore, who took Roberts to his home village. Kishore Khare, brother of Prabhakar, who drives tourists around Mumbai, has told his story.
 question: is the book shantaram based on a true story?
answer:
Yes


question:
passage: Cicuta, commonly known as water hemlock, is a small genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to 2.5 meters (8.2 ft) tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel). Plants in this genus may also be referred to as cowbane or poison parsnip. Cicuta is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas. These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of other edible and poisonous plants. The common name hemlock may also be confused with poison hemlock (Conium maculatum), or with the Hemlock tree.
 question: is water hemlock the same as poison hemlock?
answer:

No
