Another question for Torsten, or anyone familiar with ESL in German schools.

Are you familar with:

Langenscheidts Konversationsbuch English-Deutsch.

If so, can you confirm that the sentences below come from that publication?

Hier sind Schlüpfer in verschiedenen Farben. Sind sie haltbar?
“Here are panties in different shades. Are they durable?” … 00254.html

Can’t help me out, Torsten?
