Question

1 which choice provides the main ideas of the text? (ri.5.2) a in 2012, an experiment was carried out in a special lab based on a student’s idea from a contest. the experiment tested the effects of microgravity on different types of spiders. in order to learn more about microgravity, scientists sent two jumping spiders into space to study any changes in their hunting behavior. the spiders were successful hunters in space, and scientists hope this information can help them learn more about humans in space as well. c scientists experimented want to learn how insects behave in space, they sent two jumping spiders who since as part of a scientific experiment. a scientist watched the spiders to see if they changed the types of food they ate, and it was discovered that they still eat fruit flies in space. as part of an experiment, two spiders were launched in a rocket to a special lab in space. the scientists were hoping to keep track of their behavior. 2. reread the information from paragraph 3. what are earth’s oceans a sphere during in space, how are? what are some features designed by the astronauts? (ri.5.2) 4. how do astronauts train students want to space? 4. in paragraph 2, what is similar to be space? 3. is a spacesuit’s first function to space? 2. is a spacesuit’s first function to space? 1. is a spacesuit’s first function to space? (ri.5.1) 2. who are the astronauts training when they’re jumping spiders? (ri.5.1) spiderwork week 22 “spidernauts” 1 spiders in space! it’s not the title of a horror movie about live spiders in space to study their behavior. the two space spiders, lived in controlled habitats created especially for the trip. no spiders were harmed in their mission. what do you ask? eight legs in microgravity 2 the researchers were studying the effects of microgravity on the spiders that makes objects fall to earth. you may have heard that on earth, objects, people, and spiders in a space station experience gravity the same way we do on earth; they experience microgravity, also known as weightlessness. that experienced microgravity, also known as weightlessness. the feeling of hanging in the air before dropping down to bounce again is what it feels like to be weightless. a very tall roller coaster or a other carnival ride with a steep drop also creates a temporary feeling of weightlessness. student-designed experiment 3 if you have ever jumped on a trampoline, you may have experienced microgravity, also known as weightlessness. the feeling of hanging in the air before dropping down to bounce again is what it feels like to be weightless. a very tall roller coaster or a other carnival ride with a steep drop also creates a temporary feeling of weightlessness. 4 imagine how a weightless spider might act. that’s what 18 - year - old amr mohamed from alexandria, egypt, wondered when he entered the 2011 youtube space lab contest. this worldwide contest asks students ages 14 - 18 to design an experiment to be conducted onboard nasa’s international space station, a high - tech space lab 220 miles (350 km) above the earth. amr’s proposal, chosen from around 2,000 entries from more than 80 countries around the world. he asked what effect microgravity would have on jumping spiders, so two spiders in a special habitat were sent to space, where astronaut scientists studied their behavior in space.

Explanation:

1. For question 1, option B covers the core purpose of the spider space experiments: studying microgravity's effect on spider behavior, with the secondary goal of learning about human adaptation to space, which matches the text's main focus. Option A only mentions the student contest origin, which is a minor detail. Option C focuses on fruit flies, a secondary observation, not the main idea.
2. For question 2, the sentence "Without an Earth-like atmosphere doing in space, you ask?" is supported by the text's focus on studying how spiders (and other organisms) function in the microgravity/space environment, which is an investigation of space's effect on living things. The other options are too narrow: the text is not just humorous, disapproving, or focused on accounting for the spiders' trip.

Answer:

1. B. In order to learn more about microgravity, scientists sent two jumping spiders into space to study any changes in their hunting behavior. The spiders were successful hunters in space, and scientists hope this information can help them learn more about humans in space as well.
2. B. It is investigating that spiders went to space.
