Explanation:

Search engines or internet browsers are programs, software or similar that allows you to look for information on the internet or in a specific database, that provides you with results mainly based on the words you type to look for the information although other factors such as location, preferences and previous searches might have an influence. This means search engines focus on the main words you type and the way you connect those using using coordinating conjunctions such as "and, or, but, not" in case you are using more than one term or word, for example the word "not and but" will exclude some results but the word "and" would look for documents or pages in which both terms appear.

Considering this, if Deepak wants to find information from famous World War II pilots but only wants to focus on the United States pilots and not the German ones the search that will give her the results she wants is "United States pilots not German pilots in World War II" as this search include the key terms which are "United States pilots ... in World War II" but excludes the information Deepak does not want by using the word "not" which is "German Pilots.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
