Problem: Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.
What type of pressure is less than atmospheric pressure in a vacuum?

Problem: The most common way for travellers to enter the country seems to be by air. According to the website Lonely Planet, getting into Myanmar is problematic: "No bus or train service connects Myanmar with another country, nor can you travel by car or motorcycle across the border you must walk across.", and states that, "It is not possible for foreigners to go to/from Myanmar by sea or river." There are a small number of border crossings that allow the passage of private vehicles, such as the border between Ruili (China) to Mu-se, the border between Htee Kee (Myanmar) and Ban Phu Nam Ron (Thailand) (the most direct border between Dawei and Kanchanaburi), and the border between Myawaddy (Myanmar) and Mae Sot (Thailand). At least one tourist company has successfully run commercial overland routes through these borders since 2013. "From Mae Sai (Thailand) you can cross to Tachileik, but can only go as far as Kengtung. Those in Thailand on a visa run can cross to Kawthaung but cannot venture farther into Myanmar."
Is Myanmar convenient to other countries in South East Asia ?

Problem: From the 2011 Census, the Office for National Statistics published that Plymouth's unitary authority area population was 256,384; 15,664 more people than that of the last census from 2001, which indicated that Plymouth had a population of 240,720. The Plymouth urban area had a population of 260,203 in 2011 (the urban sprawl which extends outside the authority's boundaries). The city's average household size was 2.3 persons. At the time of the 2011 UK census, the ethnic composition of Plymouth's population was 96.2% White (of 92.9% was White British), with the largest minority ethnic group being Chinese at 0.5%. The white Irish ethnic group saw the largest decline in its share of the population since the 2001 Census (-24%), while the Other Asian and Black African had the largest increases (360% and 351% respectively). This excludes the two new ethnic groups added to the 2011 census of Gypsy or Irish Traveller and Arab. The population rose rapidly during the second half of the 19th century, but declined by over 1.6% from 1931 to 1951.
