Looking back, we realize that the Declaration paid no attention to many colonists. Abigail Adams, wife of delegate John Adams, tried to influence him to include women in the Declaration. It did not happen. Enslaved African Americans also had no rights under the Declaration. Slavery was legal in all colonies in July 1776. The Revolutionary War would not end the battle over slavery, even though New England states moved to end it by the 1780s. Using information from this paragraph, answer the following question:

What two groups had no rights under the Declaration?

The authors of the paper "fudging the numbers: distributing chocolate influences student evaluations of an undergraduate course"† carried out a study to see if events unrelated to an undergraduate course could affect student evaluations. students enrolled in statistics courses taught by the same instructor participated in the study. all students attended the same lectures and one of six discussion sections that met once a week. at the end of the course, the researchers chose three of the discussion sections to be the "chocolate group." students in these three sections were offered chocolate prior to having them fill out course evaluations. students in the other three sections were not offered chocolate. the researchers concluded that "overall, students offered chocolate gave more positive evaluations than students not offered chocolate." indicate whether the study is an observational study or an experiment. give a brief explanation for your choice.
