Explanation:
The first sentence is written in the past continuous tense as the use of 'was + V1 + ing' denotes that specific action was taking place in the past. It is a simple sentence as there is only a subject that is being discussed.
The next sentence employs past indefinite tense which is reflected by the use of 'V2' to signify that the action occurred at a specific time in the past. It is also a simple sentence as there is just one clause.
The third sentence uses 'past continuous tense' as it denotes that the action was in progress at a specific time in the past. It follows a simple sentence structure despite the comma after the introductory phrase as a single subject is being discussed here.
The fourth sentence uses 'past indefinite tense' as it involves V2 i.e. 'steered' to denote a past action. It involves a simple sentence structure as the single subject is followed by the predicate.
The last sentence is framed in the present perfect continuous tense which is reflected by the use of 'has been + V1 + ing' to denote that the particular action began in past and is in progress now. It also follows a simple sentence structure as the only subject 'My brother' is being talked about here.
