omeli [17]

Answer:

Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contes t is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating. Part A: What is the main idea of the paragraph that begins "Just to clarify," and explains how contestants count sightings? Fill in blank 1 using A, B, C, or D. A. The contest lasts for only one year and requires little evidence. B. These birders use an honor system because most love birding more than winning. C. The number of sightings typical "Big Year" birders see is amazing. D. The typical records are very hard to break within the time frame. Part B: Select one quotation from the text that supports your answer to Part A. Enter your selection in blank 2 using E, F, or G. E. The birds these contestants are counting are the number that they see in a particular year. F. No pictures or other evidence is required as proof of a sighting. G. Most birders take great pride in their reputation and their abilities. Sele. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating. I.

WITCHER [35]

English I, II Bell Ringer

Weeks 21/22, Day 1/ 2

LA.910.1.7.7 The student will compare and contrast elements in multiple texts

(e.g., setting, characters, and problems).

Read the passage and select the best answer.

Scott started nodding off in class. Mrs. Thomas tapped his desk as she passed it.

They started off the school year without a teacher and now that they had a teacher

they missed the substitute teachers. The class took advantage of every substitute

teacher that came in to teach. They would take turns dropping books, pass notes all

period, and take turns pretending to sneeze. Each day a different substitute teacher

would show up and every day they did everything they could think of to annoy

him or her. No one learned anything. The new teacher put an end to their antics.

The more disruptive they were, the more homework they received. It was bad

enough that she gave a ton of homework every night no matter how well behaved

they were. Scott looked over at his teammate Brian and smiled. He couldn’t wait

until the track meet this afternoon. Brian was an expert at the hurdles and Scott

was king of the long jump. Scott was having difficulty in school lately. He was

more interested in staying up late watching television and he was having difficulty

staying awake in class as a result. Brian was also struggling but he was having

trouble sleeping at night due to family problems. It seemed lately that his parents

arguments became louder and louder every night.

I DO

1. According to the passage how are Scott and Brian alike?

A. Both are on the football team.

B. Both are doing poorly in school.

C. Both are having family problems.

D. Both are happy to have a new teacher.

WE DO

2. How did the student’s problem in the story change?

A. In the beginning they had a teacher and in the end they had substitute teachers.

B. In the beginning they had substitute teachers and in the end they did not get enough

homework.

C. In the beginning they weren’t learning anything and in the end they were getting too much

homework.

D. In the beginning the substitute teachers were giving too much homework and in the end they

weren’t learning anything.

indicate that Scott is having family problems.

Choice D – This answer is not correct because there is nothing in the passage to

indicate that either one is happy to have a new teacher.

2. Explanation of the correct answer:

Choice A –This answer is not correct because the passage states that they had

substitute teachers at the beginning and at the end they had a teacher.

they received a ton of homework.

Choice C –This answer is correct because the passage states that in the

beginning they took advantage of the substitute teachers and did not learn

anything. In the end their teacher gave a ton of homework.
