The best way to improve the paragraph's sentence fluency is to correct the sentence fragments. The current structure includes incomplete sentences, particularly the first two sentences, which should be combined for clarity and coherence.
Here’s a revised version of the paragraph:
Salvador Dalí, born Salvador Felipe Jacinto Dalí y Domenech in Figueras, Spain, in 1904, was a Surrealist painter and printmaker. Some of his most notable works explore subconscious imagery, and he was profoundly influenced by the writings of Sigmund Freud, an Austrian neurologist who created psychoanalysis.
This revision corrects the fragments and improves the overall flow of the paragraph by creating complete sentences.
