Sentence Analysis
As we read the sentence, we figure out that the sentence presents a comparison of the success one person achieved in two different time periods. It says that:
‘she’ (some ‘she’ – we don’t have an antecedent till now) was less successful after she had emigrated to New York than she had been in her native Germany.
As you can see, while presenting the comparison, I’ve changed a couple of things.
‘compared to” to “than” – When we have less, more, or other -er words (better, smaller etc), we need ‘than’, instead of ‘compared to’ or other comparison structures, to follow these words.
‘compared to her native Germany’ to ‘than she had been in her native Germany’ – As is, the original sentence seems to compare ‘she’ with ‘her native Germany’. Clearly, not only the meaning is illogical but it also doesn’t seem to be the intended meaning.
Therefore, while explaining this part of the sentence, I’ve made the above two changes. It also means that these two are the errors that need to be corrected.
As we read further, we see that there’s another independent clause:
photographer Lotte Jacobi nevertheless earned a small group of discerning admirers
We have two independent clauses joined by a comma. This is the third error in the sentence.
In addition, since the first part of the sentence is an independent clause, it doesn’t make sense to use the pronoun ‘she’ in it and then introduce the antecedent in the second independent clause. If these two parts are to be presented as two independent clauses, then ideally, the noun should be used in the first independent clause and the pronoun in the second independent clause.
