Is this “there’s” or “this”? Need help with listening!!

I was doing an IELTS listening practice and misheard “there’s” as “‘this”.

I don’t hear the /e/ sound …

Which one do you hear?

I opened the audio in Praat, but I’m not sure how to identify the formats for “there’s” vs.”this”. Could someone help me confirm which sound it actually is?
