The following is a student draft. It may contain errors.
One example of scientists working to make people's lives better is through their development of underwater greenhouses, a sustainable method for producing food. One underwater greenhouse, a set of pods anchored to the sea floor just outside the coast of Italy's Liguria Region, is called Nemo's Garden.
Nemo's Garden was developed in 2012 by a company called the Ocean Reef Group. Through their experiments at Nemo's Garden, the group was able to learn that plants grow faster underwater. This discovery led the scientists to conclude that underwater greenhouses could be one way to ensure that countries experiencing drought or other conditions that impact farming would still have access to healthy food.
The pods found in Nemo's garden look similar to something one would see in a science fiction movie. The pods are various sizes and float at different depths, which keeps the plants safe. The dome at the top of each pod allows sunlight to enter, which keeps the plants warm despite the fact that the surrounding water is much cooler.
The crops in Nemo's Garden must remain hydrated to grow. Additionally, the plants must be maintained by a special group of divers and monitored twenty-four hours a day through the use of cameras and sensors.
While underwater greenhouses are not without problems—mainly due to leaking and decay—scientists are hopeful about their potential future uses.

Read the statement from the draft.

"The crops in Nemo's Garden must remain hydrated to grow."

Which detail would be best to add after this first sentence from paragraph 4 to support the statement?

A.
To make sure crops are watered, the greenhouses are designed to cause water to condense into droplets then drip down the sides of the pods into the plants.
B.
Greenhouses can become very hot and cause the plants to dry out, which is why they need a constant supply of water.
C.
Hydration is an important part of the growth cycle of any plant, but it is particularly important for maintaining the health of plants grown in underwater greenhouses.
D.
If the plants do manage to become dried out, they will need to be rehydrated almost immediately.

An expository essay instructs, provides information, or explains. in this essay, you are presenting information and explaining why you think the ideas and work of the individual you chose had an effect on european thought. but before you begin writing the essay, you need to organize the information you’ve gathered by creating an outline. directions: your taking notes sheet should have you identify and organize the information you found while doing your research. now it is time to create an outline to organize the information in the way you will present it in your essay. you may decide not to use all the information you gathered, but be sure you do not leave out anything that you believe is important to support your thesis. your essay should include an introductory paragraph, supporting paragraphs, and a concluding paragraph. each paragraph should cover one main topic and should correspond to a roman numeral (i., ii., iii.) on the outline. the main topics should cover: the person’s accomplishment and contributions, and the effect of his or her accomplishments or contributions on european thought. write a topic sentence for each paragraph of your essay. be sure it tells the reader what the section will be about and how the information relates to your thesis statement. your topic sentence for the introductory paragraph might say something like “johannes gutenberg’s invention changed the way people communicated.” a topic sentence for the second paragraph—the first main topic—might be something like "gutenberg’s printing press changed the way books were produced and the way knowledge was communicated.” decide which pieces of information you will use to support your topic sentences. (these ideas or groups of facts are called subtopics.) subtopics follow capital letters and periods (a., b., and c.) on your outline. add this information beneath your topic sentence. you can further divide subtopics into specific facts. in an outline, specific facts follow arabic numerals and periods (1. 2. 3. 4.) end your outline and essay with a concluding paragraph. write a concluding paragraph that summarizes the main ideas of your essay and restates your thesis statement in some way. write no more than four or five sentences. worth 241 points
