The mistakes:
• “I hear you will go to Paris last month”
Should be- “I heard you went to Paris last month.”
• “I am sure you will.”
Should be- “I’m sure you did.”
• “Will you see Sophia...”
Should be- “Did you see Sophia...”
• “I did heard Ridley...”
Should be- “I did hear Ridley...”
• “I will see our old friend Steven Eastwood last week.”
Should be- “I saw our old friend Steven Eastwood last week.”
• “He will be doing very well.”
Should be- “He was doing very well.”
• “It was called U.T...
Should be- “It is called U.T...”
• “You must saw it.”
Should be- “You must see it.”

That’s all! The main problem through out this passage was the tenses. The mistakes should be put into past tense.

Hope this helps; have a good day! :)
