Morning,
There are some mistakes in the teacher's guide and are being corrected now.
For now, all you need to know is that (The two sounds /t/ and /d/ are elided when they are found between two other consonants).
Example
I don’(t) know.
I watch(ed) TV las(t) night.
In the exam you will have a simple clear example.
Good Luck
Ola. M 🌷
