The war was successful for Great Britain, which gained the bulk of New France in North America, Spanish Florida, some individual Caribbean islands in the West Indies, the colony of Senegal on the West African coast, and superiority over the French trading outposts on the Indian subcontinent. The Native American tribes were excluded from the settlement; a subsequent conflict, known as Pontiac's War, was also unsuccessful in returning them to their pre-war status. In Europe, the war began disastrously for Prussia, but a combination of good luck and successful strategy saw King Frederick the Great manage to retrieve the Prussian position and retain the status quo ante bellum. Prussia emerged as a new European great power. Although Austria failed to retrieve the territory of Silesia from Prussia (its original goal) its military prowess was also noted by the other powers. The involvement of Portugal, Spain and Sweden did not return them to their former status as great powers. France was deprived of many of its colonies and had saddled itself with heavy war debts that its inefficient financial system could barely handle. Spain lost Florida but gained French Louisiana and regained control of its colonies, e.g., Cuba and the Philippines, which had been captured by the British during the war. France and other European powers avenged their defeat in 1778 when the American Revolutionary War broke out, with hopes of destroying Britain's dominance once and for all.
What happened to the scope of France's colonies as a result of the war?
France was deprived of many of its colonies

The city also boasts an efficient network of public transportation, which mainly consists of bus, taxi and metro systems. The bus network, which is currently run by three companies since 2011, provides more than 370 routes covering all parts of the city and suburban areas. Nanjing Metro Line 1, started service on September 3, 2005, with 16 stations and a length of 21.72 km. Line 2 and the 24.5 km-long south extension of Line 1 officially opened to passenger service on May 28, 2010. At present, Nanjing has a metro system with a grand total of 223.6 kilometers (138.9 mi) of route and 121 stations. They are Line 1, Line 2, Line 3, Line 10, Line S1 and Line S8. The city is planning to complete a 17-line Metro and light-rail system by 2030. The expansion of the Metro network will greatly facilitate the intracity transportation and reduce the currently heavy traffic congestion.
How many stations are there in total in the Nanjing metro system?
121 stations

In Darwin's time there was no agreed-upon model of heredity; in Chapter I Darwin admitted, "The laws governing inheritance are quite unknown." He accepted a version of the inheritance of acquired characteristics (which after Darwin's death came to be called Lamarckism), and Chapter V discusses what he called the effects of use and disuse; he wrote that he thought "there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited", and that this also applied in nature. Darwin stated that some changes that were commonly attributed to use and disuse, such as the loss of functional wings in some island dwelling insects, might be produced by natural selection. In later editions of Origin, Darwin expanded the role attributed to the inheritance of acquired characteristics. Darwin also admitted ignorance of the source of inheritable variations, but speculated they might be produced by environmental factors. However, one thing was clear: whatever the exact nature and causes of new variations, Darwin knew from observation and experiment that breeders were able to select such variations and produce huge differences in many generations of selection. The observation that selection works in domestic animals is not destroyed by lack of understanding of the underlying hereditary mechanism.
What did Darwin speculate might be how inheritable variations might come about in a species?
environmental factors
