1. Winslow Homer's picture is called (P) Shark Fishing (RDO) [#1]. |

4. John and Mary named their dog Barky [#2]. |

5. My family is going {to Ocean City} {in July}. |

6. Bill, Mary, Sally, and Randy are waiting {for Easter vacation}. |

7. My teacher's name is Mrs. Sabrina Thompson (PN). |

8. Are there [#3] pine trees {in Rocky Mountain National Park} {near Denver, Colorado}? |

1. "RDO" stands for a retained direct object after a passive verb. [See KISS Level 5.7 - Passive Voice and Retained Complements.] I would expect students to mark it as a complement because it answers the question "what?" after "is called."
2. I would expect most students to mark "dog" as a complement. Later, they will learn that "dog" is the subject and "Barky" is a predicate noun to an ellipsed infinitive "to be"--"dog *to be* Barkey." 
3. This "there" will confuse many students. It can be viewed as an adverb or as the subject, which would make "trees" a predicate noun. [See KISS Level 2.1.3 - Expletives (Optional).]
