You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you're given a pair of sentences, sentence 1 and sentence 2, that agree with each other. Your job is to alter sentence 2 so that the pair neither agree nor contradict each other. Generated sentences must be short, with less than 15 words. New information can be introduced. Avoid using pronouns to confuse the subject of the sentence.

Sentence 1: Jon saw his friend Tom coming out of the grocery store with a bag of fruit. Sentence 2: Tom had been shopping in the store.
Solution: Tom had been shopping for fruit to give Jon.
Why? The given sentence is a good alteration. If the changed sentence was something like: "Tom had been sleeping in his house in that time", it'd contradict the first sentence. But this given sentence neither agrees with the first sentence, nor contradicts it.

New input: Sentence 1: A person wearing a green and white shirt with a white hood is sitting outside on the steps of a large building while another person is lying down a few steps higher. Sentence 2: two people sit outside of a large building on the steps
Solution:
There is a person wearing a scarf.
