In the preface from The Pluto Files, Tyson writes that Pluto has a "remarkable grip on the hearts and minds of the American public." In the NPR interview, he jokingly says that he's blaming Disney and Mickey's dog, Pluto, for America's fascination. Why do you think he takes a more lighthearted tone during the NPR interview?

Answer and Explanation:

He takes on a more cheerful tone to make the interview more "palatable" to the public, that is, he knows that the interview is seen and heard by the most different types of audience, so to make the interview lighter and more comprehensive for everyone, allowing his words reach the most varied types of people, he prefers to use a funnier and more relaxed tone, allowing empathy between him and the audience and a greater acceptance of the ideas he has to speak.

angel island immigration station was an immigration station located in san francisco bay which worked from 1910 to 1940. the majority of immigrants that got there were from the asian hemisphere, specifically from china, japan, russia, and south asia, being china the country from where more people arrived.

the number of foreigners arriving at it took the attention of americans who feared the new arrivals would take their jobs. the work opportunities were not abundant due to the economic comedown of 1870 and the asians, as newcomers, were willing to work for cheaper wages. soon they started to be seen as a threat, which led to an increased discrimination against the chinese - the biggest ethnicity arrived at this station until 1915 when japanese immigrants outnumbered them - being considered as unsuitable americans hence their looks and social situation.

at the station, the immigrant's detention may vary depending on how long the interrogation process took: it could be weeks, months, or even years.

finally, in 1940 an explosion destroyed administration building located on the island, so the united states government decided to stop the process.
