The sentence that best corrects the original one is option 3) “Noticing that the patio table had been turned over by the storm, Anton flipped it back on its feet.”
In this option, we make it clear that the doer of the action (flipping back the table) is Anton and in the original sentence is not mentioned.
The first option is incorrect since it says that the storm flipped back the chair instead of Anton.
Option number two is also incorrect since the meaning is not clear, especially the 2nd part of the sentence.
And the last option is also incorrect because it uses the passive voice in both parts of the sentence, when it should be using acting voice in the 2nd part, making emphasis on the doer of the action (Anton) rather than on the action itself.
The difference between observation and data is that observation is whatever you noticed happening such as, something dissolved or changed form or melted. Data is what ever measurements you made or took. Data is the actual information but observation is what you are seeing not whats actually involved.
