Which of the following is a sound argument?
"if the moon is made of cheese, then donald trump is the president of mexico. the moon is made of cheese. therefore, donald trump is the president of mexico."
"either turkey is a country or new york is a country. new york is not a country. so turkey must be a country."
"i have seen millions of black crows. therefore, all crows must be black."
"if the earth is flat, then ted cruz is the president of the united states. the earth is not flat. therefore, ted cruz is not the president of the united states."

i believe it’s the first one, but it could be the second! not the third or fourth.

explanation:

free time is when all my homework and chores have been done for the day and i am "free" to do things that i enjoy doing.

usually i spend time watching television. as my favorite tv shows come on at specific times, i make sure that i finish my homework and chores well before the shows. otherwise i will have to miss them. mostly i manage to watch the shows but sometimes extra homework or chores may cause me to miss a show or two, but it is rare. anyhow if i know that i am definitely not able to catch a show in time, i will just set the video recorder to tape the show sothe evening when the weather is fine, i sometimes go for a stroll around the neighborhood with my friends. this is the time when most the neighbors have come home from work or school. we say hello to those whom we know. they are mostly friendly people and they acknowledge our greetings. once in a while we come upon unfriendly neighbors but we just ignore them and carry on. that i can watch it later.

may i know the title of the book?
