Explanation:
All of the phrases that are a no, can be identified by removing 'to' from the phrase. Is the second word a verb? If not, then it isn't a verbal.
For example: Lana waits to see if ships go to sea. When we remove 'to', the word 'sea' is left. Sea is not a verb, so number 3 is not a verbal phrase.
