Nepal is a landlocked Asian country bordered only by China and India, which happen to be the two most populous nations on Earth.  Nepal is bordered to the north by China, and to the south, east, and west, by India.  Nepal is separated from Bangladesh by the narrow Siliguri Corridor, which is part of India.

Lines of latitude, also called "parallels," measure the angular distance of points north and south of the Equator. On maps, they appear as horizontal lines across the surface of the Earth.

A dot map may easily be used to demonstrate the distribution of a particular item across a space. Here, dots may be used to represent each federal prison and its location across a map of the United States.

Whilst it is true that political concerns can sometimes impede the pursuit of an accurate depiction of the world this is not the primary reason why it is so difficult to produce an accurate map. The primary reason is that the world is a three-dimensional object (a sphere) and a map is a two-dimensional object (usually a rectangle). When a three-dimensional object is reproduced on a two-dimensional surface some aspects are naturally, and unavoidably, distorted. The challenge for many mapmakers is how to reduce this distortion, or rather how to provide the most accurate depiction of the world.

Geographers use a coordinate system to describe the location of any particular place on Earth. The coordinate system is made up of lines of longitude and lines of latitude. Lines of longitude—also called “meridians”—begin at the North Pole and make their way “up and down” the Earth to the South Pole. All lines of longitude eventually meet at the poles (i.e. time zones such as Eastern Standard Time or Greenwich Mean Time). On the other hand, lines of latitude make their way around the Earth and never intersect with each other; they are often also called “parallels” (i.e. the equator). 

“Isolines” are used primarily in topographical maps. The topography of a region refers to its elevation and the changes in its elevation; therefore, isolines are used to demonstrate elevation.

The Ptolemy Projection and The Eratosthenes Projection are not actual map projections so neither of these could be correct answers. The Mercator Projection specifically emphasizes accurate direction, but in doing so distorts land size. The Peters Projection is an attempt to accurately reflect the land size of all continents equally, but in doing so it distorts distance and direction. The Robinson Projection is something of a compromise in that it attempts to minimize errors in distance, relative size, and compass direction but does not accurately depict any one of these factors wholly.

The Mercator Projection was an attempt to create a two-dimensional map that maintained accurate and reliable compass points, and in this it succeeded, but, unfortunately, in doing so it distorted the area of continents and landmasses relative to each other. In the Mercator Projection as you get further from the equator the landmasses become larger and larger compared to how they would accurately be projected. This means that Antarctica and Greenland look much larger than they should appear.

The “international dateline” is on the opposite side of the planet to prime meridian. Whereas prime meridian is found at 0’, the international dateline is found at 180’. The international dateline is the point where each day begins for the first time, it is found in the Pacific Ocean.

The “resolution” of a map refers to the smallest thing that can be recorded on the map. For example a map of the United States might only show cities with a population of five hundred thousand or more, so a city with a population of four hundred thousand would fall outside of the resolution of the map. The ratio between map distance and actual distance is known as the “scale.”
