Finland
Explanation:
Out of the numerous countries that are members of the European Union, Finland is the one with the smallest population density. The country is relatively large for European standards, but it has very small population. The population density of this Northern European nation is 16 people per square kilometer, which is far beyond the average for the European Union. The reason for this is mostly the climate. Finland is one of the coldest countries in the world. Big portion of the country has very harsh conditions for living, so naturally the people don't live in those areas. Also, the lakes are occupying lot of the territory of this country, thus reducing the area where the living conditions are bearable. Most of the population lives in the southern part of the country, being either along the coastline, or very close to it.

Explanation: GPS which is an acronym for Global Positioning System is a global satellite based location and navigation system owned by the US Government. It was first used by the US Air Force in 1978. It's main purpose is to show a GPS user location and time information from anywhere on earth, where there is an unobstructed line of sight from the precise location to 4 or more GPS satellites. GPS is commonly used on land (obviously through every day use like when you use an uber) and in the air (pilots use GPS signals when they fly).
GPS can be used to track pets if there's a tracking device on their collars.
GPS is also used in taxis and can be used to track a cab after a hurricane.
Ordinary people can use GPS to collect information for scientists - an example of this would be taking a new undefined route on Google maps therefore adding to their archive of known routes/areas.
However GPS signals cannot penetrate water - sea water especially. Hence the answer is B
because they're different ways
