Problem: History of India:

The Nawab of Bengal Siraj Ud Daulah, the de facto ruler of the Bengal province, opposed British attempts to use these permits. This led to the Battle of Plassey on 23 June 1757, in which the Bengal Army of the East India Company, led by Robert Clive, defeated the French-supported Nawab's forces. This was the first real political foothold with territorial implications that the British acquired in India. Clive was appointed by the company as its first 'Governor of Bengal' in 1757. This was combined with British victories over the French at Madras, Wandiwash and Pondichéry that, along with wider British successes during the Seven Years' War, reduced French influence in India. The British East India Company extended its control over the whole of Bengal. After the Battle of Buxar in 1764, the company acquired the rights of administration in Bengal from de jure Mughal Emperor Shah Alam II; this marked the beginning of its formal rule, which within the next century engulfed most of India. The East India Company monopolized the trade of Bengal. They introduced a land taxation system called the Permanent Settlement which introduced a feudal-like structure in Bengal, often with zamindars set in place.

What type of land taxation system did the East India Company instigate in Bengal?
---
A: feudal


Problem: Zhejiang:

Despite the continuing prominence of Nanjing (then known as Jiankang), the settlement of Qiantang, the former name of Hangzhou, remained one of the three major metropolitan centers in the south to provide major tax revenue to the imperial centers in the north China. The other two centers in the south were Jiankang and Chengdu. In 589, Qiangtang was raised in status and renamed Hangzhou.

 What is the current name of Hangzhou?
---
A: unanswerable


Problem: Dog:

Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, "Chaser", who had learned the names and could associate by verbal command over 1,000 words. Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands. Dogs demonstrate a theory of mind by engaging in deception. A study showed compelling evidence that Australian dingos can outperform domestic dogs in non-social problem-solving experiment, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans. Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not. Modern domestic dogs use humans to solve their problems for them.

What is the name of the Border collie that knew over 1000 words?
---
A: Chaser


Problem: Bacteria:

Bacterial species differ in the number and arrangement of flagella on their surface; some have a single flagellum (monotrichous), a flagellum at each end (amphitrichous), clusters of flagella at the poles of the cell (lophotrichous), while others have flagella distributed over the entire surface of the cell (peritrichous). The bacterial flagella is the best-understood motility structure in any organism and is made of about 20 proteins, with approximately another 30 proteins required for its regulation and assembly. The flagellum is a rotating structure driven by a reversible motor at the base that uses the electrochemical gradient across the membrane for power. This motor drives the motion of the filament, which acts as a propeller.

When flagellum is distributed throughout the surface of the cell?
---
A:
peritrichous
