In chapter 11, Mrs. Tibbits and Ben just get back from toad watching because it was raining. Mrs. Tibbits tells Ben the reason why her sister-in-law wants to sell the house. Developers want to purchase the property to build on it. Ben realizes this is not good because the Spadefoot toads are endangered and if developers indeed purchase the property and build there, the spadefoot toads will no longer be able to lay their eggs and will probably become extinct. Ben is trying to hatch a plan to help Mrs. Tibbits in this situation.
The main idea of the paragraph is that women should be credited for much more during the prehistoric times that they are at the moment. We only get the picture of them being rather irrelevant at the time which is obviously not true, based on this excerpt. The paragraph is quite feminist, meaning that it is shedding light on actual history and the role of women in such a society which not much is spoken about in contemporary analyses.
They were the ones who invented gardening, as well as pottery and weaving. The reason why they did this was because they often stayed 'at home' taking care of children, so they had time to do other things as well, while men were out hunting and providing for the family in other ways. Thus we have solid proof that women were far more creative and responsible for various things than they are credited for now.
The correct answer is option 3: "Tonight, Shea read a short story, practiced soccer, and chatted with Betsy". Remember that whenever you need to use parallel structures, you have to use <u>the same tense or word pattern</u>. In option 3, you have three verbs. The three of them are in the past simple tense. Option 1, "Last evening, Shea read "The Necklace", study her physics, and to buy her prom dress" is not grammatically correct. That sentence presents different tenses and the verbs are not well conjugated. Therefore, It is not written in proper parallel structure. Option 2, "Yesterday, Shea bought her dress, had completed her calculus problems, and was talking to Bobby" is not grammatically correct either. Although the sentence is stated in the past, the order of the events is not clear and the verbs do not belong to exactly the same tense. To conclude, option 3 is the only sentence written in proper parallel structure.
Photosynthesis produces oxygen and glucose mainly. The oxygen gets released into the air, because oxygen to plants is like carbon dioxide to us. It doesnt harm them, but they cant use it. The glucose ends up either being used by the plant or stored somewhere within the plant to be used later.
