I forgot to include the following sentences.Thank you very much.

1) This hotel is more convenient since it lies near the school. They (it?) charge 60 Euros for a single rooom and 90 for a double room.
2) Thank you very much for your decision of helping me finding a school interested in joining our project.
Hopefully you manage to find it before our deadline.
3) I apologize for sending the same sentences to you twice but it was late and I realized it only later

To include those sentences, you can simply copy and paste them into your message or email. Here's how you can do it:

1) If you are writing an email or a message, continue writing your main text and then press "Ctrl + V" (or "Command + V" on a Mac) to paste the sentences.

2) If you are using a word processing software like Microsoft Word, open a new document and click on the area where you want to include the sentences. Then press "Ctrl + V" (or "Command + V") to paste them.

3) If you are using a text editor, such as Notepad or TextEdit, open a new document and click on the area where you want to include the sentences. Then press "Ctrl + V" (or "Command + V") to paste them.

Remember to proofread your message or document after pasting the sentences to ensure everything is correct and in the right place.
