grammar usage:ｘもｙもｚもあります vs ｘとｙとｚはあります

Question

I read the first sentence in a graded reader, and I'm wondering why the author chose the first grammar pattern over the second.

絵本{えほん｝もピアノもテレビもあります。

絵本とピアノとテレビがあります。

What is the difference in meaning between these two phrases, or, if the meaning is relatively similar, why would you choose to use one over the other?

Answer 1

See in depth explanation: Use of も in this sentence.

In brief

• 絵本もピアノもテレビもあります translates roughly to "There are (many things such as) picture books, a piano, and a television."
• 絵本とピアノとテレビがあります translates roughly to "There is a picture book, a piano, and a television (and that's exactly it)."
