Find evidence t supprt yur chice.
Space agencies f varius cuntries are planning manned missins t Mars that culd take place within the next 25 years.
1 “Humans have yet nt visited Mars” can be inferred frm paragraph 3.
In the 1960s and 1970s, the greatest fear was that the human race, and pssibly all advanced life frms n the planet, culd be wiped ut by nuclear missiles, just at the push f a buttn.
4 “The greatest risk t life n Earth used t be nuclear missiles” can be inferred frm paragraph 1.
Scientists are thinking f ways t lwer this risk, such as replacing cal and il with frms f renewable energy.
6 “Our Plan A includes develping renewable energy resurces” can be inferred frm paragraph 1.
As early as the 1980s, scientists were building Bisphere 2 in the Arizna desert… Althugh the tw-year experiment was nt a success, it did prvide us with a better understanding f hw humans might be able t live n anther planet.
7 “The Bisphere 2 experiment ended in failure” can be inferred frm paragraph 4.
Smetimes, we need t frm pinins and draw cnclusins that are nt directly stated within the given infrmatin. Fr example, frm the sentence “While the Mn can be reached within days, it wuld take mnths t reach Mars, travelling thrugh dangerus slar radiatin”, we can infer that the Mn is less expsed t dangerus radiatin than Mars. Headings and pictures can als help us make educated guesses abut a text.
