The presentation should be about twelve slides in length. Your presentation will include: • Title • Introduction – gives an overview of the presentation • Time line of missions – must include 3 manned and 3 unmanned missions • Description of each of the missions in the timeline (1 mission per slide) (a) Name and date of mission (b) Purpose of missions (c) Results or findings from missions • Scientific advance – describe a scientific advancement that has led to an engineering improvement in space exploration • Engineering advance – describe an engineering advance that has led to greater knowledge about the solar system • Sources – list the websites and other sources you used Remember to make a list (i. e., bullet points) on each slide. The slides should feature the highlights of the main idea. The bullet points should be short phrases (at most, one sentence) that highlight key points. PLS HELP WILL MARK BRAINLEST

Scientist: cross-sections of stalactites—calcite formations deposited on cave ceilings by seeping water—can reveal annual variations in rainfall in particular areas over hundreds and thousands of years. we often found that when—according to these cross-sections—drought occurred in a particular area, it coincided with the collapse of an ancient society in that area. i hypothesize that drought reduced agricultural productivity in these areas, thereby leaving these societies without the resources needed to handle internal stresses and external threats. which of the following, if true, would most weaken the support for the scientist's hypothesis? a. many droughts indicated in the cross-sections of stalactites do not correspond with the collapse of a society in that area. b. information from the cross-sections of stalactites alone cannot reveal the level of agricultural output in an area at a particular time. c. most of the societies that collapsed during droughts did so when internal power struggles coincided with military raids from neighboring societies. d. most of the societies that collapsed during droughts maintained large stockpiles of food and water at the time of their collapse. e. information from stalactites also suggests that the collapse of some societies coincided with periods of abnormally high rainfall.
