Past Simple Transformation
Transformation Rule: To convert sentences to the past simple tense, change the present tense verb to its past tense form. The contraction 'It's' stands for 'It is'. The past tense of 'is' is 'was'.
Step-by-step Solution:
- Identify the present tense verb: 'is' (in 'It's').
- Find the past tense of 'is', which is 'was'.
- Replace 'It's' with 'It was' in the sentence.
