Hi,
Greg has advised not to summarize or conclude the essay but in one of the sample responses in the TOEFL Official guide, I saw that the passage summary is indeed written.
Is it needed for a high score like 5?
Essay’s ending:
Another interesting fact is, that the main panel is made from the same tree like another painting of Rembrandt, ‘Selfportrait with a hat’.
In the end it is clear that this painting is indeed a work of the Dutch painter and it
should be reintegrated in the catalog of Rembrandt’s paintings.
