In New York City in 1846, Alexander Turney Stewart established the "Marble Palace" on Broadway, between Chambers and Reade streets. He offered European retail merchandise at fixed prices on a variety of dry goods, and advertised a policy of providing "free entrance" to all potential customers. Though it was clad in white marble to look like a Renaissance palazzo, the building's cast iron construction permitted large plate glass windows that permitted major seasonal displays, especially in the Christmas shopping season. In 1862, Stewart built a new store on a full city block with eight floors and nineteen departments of dress goods and furnishing materials, carpets, glass and china, toys and sports equipment, ranged around a central glass-covered court. His innovations included buying from manufacturers for cash and in large quantities, keeping his markup small and prices low, truthful presentation of merchandise, the one-price policy (so there was no haggling), simple merchandise returns and cash refund policy, selling for cash and not credit, buyers who searched worldwide for quality merchandise, departmentalization, vertical and horizontal integration, volume sales, and free services for customers such as waiting rooms and free delivery of purchases. His innovations were quickly copied by other department stores.
What customer services did the Marble Palace offer? 
****
The answer: waiting rooms and free delivery of purchases

Hokkien dialects are typically written using Chinese characters (漢字, Hàn-jī). However, the written script was and remains adapted to the literary form, which is based on classical Chinese, not the vernacular and spoken form. Furthermore, the character inventory used for Mandarin (standard written Chinese) does not correspond to Hokkien words, and there are a large number of informal characters (替字, thè-jī or thòe-jī; 'substitute characters') which are unique to Hokkien (as is the case with Cantonese). For instance, about 20 to 25% of Taiwanese morphemes lack an appropriate or standard Chinese character.
What is another name for standard written chinese?
****
The answer: Mandarin

In many people, the infection waxes and wanes. Tissue destruction and necrosis are often balanced by healing and fibrosis. Affected tissue is replaced by scarring and cavities filled with caseous necrotic material. During active disease, some of these cavities are joined to the air passages bronchi and this material can be coughed up. It contains living bacteria, so can spread the infection. Treatment with appropriate antibiotics kills bacteria and allows healing to take place. Upon cure, affected areas are eventually replaced by scar tissue.
What type of bacteria-attacking medicine will treat tuberculosis?
****
The answer: antibiotics

The empire went into decline thereafter. The Mughals suffered several blows due to invasions from Marathas and Afghans. During the decline of the Mughal Empire, several smaller states rose to fill the power vacuum and themselves were contributing factors to the decline. In 1737, the Maratha general Bajirao of the Maratha Empire invaded and plundered Delhi. Under the general Amir Khan Umrao Al Udat, the Mughal Emperor sent 8,000 troops to drive away the 5,000 Maratha cavalry soldiers. Baji Rao, however, easily routed the novice Mughal general and the rest of the imperial Mughal army fled. In 1737, in the final defeat of Mughal Empire, the commander-in-chief of the Mughal Army, Nizam-ul-mulk, was routed at Bhopal by the Maratha army. This essentially brought an end to the Mughal Empire. In 1739, Nader Shah, emperor of Iran, defeated the Mughal army at the Battle of Karnal. After this victory, Nader captured and sacked Delhi, carrying away many treasures, including the Peacock Throne. The Mughal dynasty was reduced to puppet rulers by 1757. The remnants of the Mughal dynasty were finally defeated during the Indian Rebellion of 1857, also called the 1857 War of Independence, and the remains of the empire were formally taken over by the British while the Government of India Act 1858 let the British Crown assume direct control of India in the form of the new British Raj.
Who was the final Commander-in-chief of the Mughal army?

Nizam-ul-mulk
