On the first day of school, Mr. Haddad told his 9th grade classes, "You are in high school and old enough to know right from wro
ng. As long as you behave, we can have a lot of fun in this class. I plan to allow many opportunities for interaction and games. I don't have a list of rules, but I do expect that you will behave yourselves. If you have any questions about how to behave, just raise your hands now and I'll answer questions." (Pauses for awhile.) "OK, let's get started looking at our course. I will hand out my course description and go over my grading criteria and course requirements." A potential difficulty with Mr. Haddad's beginning is that a. he has no expectations for student behavior or class proceduresb. he should not question students on the first day.c. appropriate behavior in important areas may not be adequately understood by the students.d. b and c only.e. a, b, and c are all correct.
Mary Malton is popularly called as Typhoid Mary as she was the cause of typhoid outbreak in the US.
Explanation:
Mary Mallon was born in 1869 in Ireland and then moved to the US in 1884. She did various works to earn her living like doing laundry and cooking. She was stubborn and denied being ill and spread the disease to many people.
She was isolated for several weeks but even after that, she continued to host the bacteria and spread the disease. Immunization was not discovered in those days and many people were infected.
One fine day, she had a stroke and never walked. Then she was moved to Riverside Hospital and then she died.
