Please help me understand these syntax trees (French and English). For context we are learning about the representation of movement in syntax trees. From my understanding, we'd have to use an X' under the first SV and then continue from there? So it is not possible to have SV then SV again? Another understanding I have is that we can have another node but of a different type?
Are the first two valid? Is the third one valid? Are they all incorrect?
ST = Tense Phrase, SN = Noun Phrase, T = Tense, SV = Verb Phrase, SAdv = Adverb Phrase
Phrase 1 : Ada visite toujours les musées.
Phrase 2 : Ada always visits museums.
