Manjiro wondered why the foreigners didn’t just carry their small things in separate pouches, the way it was done in Japan. But once his hands discovered his pockets, he couldn’t keep them out. His hands wanted to explore those spaces just like, when he’d lost teeth as a boy, his tongue wanted to explore the empty holes where his teeth had been.

Which words best show Manjiro’s curiosity?

“lost” and “the empty holes”
“wondered” and “wanted to explore”
“foreigners” and “separate pouches”
“carry” and “the way it was done”
