<p>Find the error:
Soil samples brought into the Viking lander were sent to the three separate biological laboratories to be tested in different ways for (indications of the presence of living things.)</p>
<p>Fix in parenthesis</p>
<p>Choices:
A. No change
B. the existence of life.
C. indications that living things exist there.
D. the presence of living things indicating life.</p>
<p>The answer is No change. Please EXPLAIN!!!!!!</p>
<p>B is wrong because their not being tested “for” the existence of life.
C is grammatically incorrect. (“indications” doesn’t ‘agree’ with “that.”)
D is awkward not sure if there is something else technically wrong with it as well.</p>
<p>what is the idiom for test?</p>
<p>B. Too general. We know that life exists.
C ‘There’ refers to the laboratories.
D The presence of living things doesn’t ‘indicate’ life; it IS life.</p>
<p>B) the exams are performed for the research of indications which can lead to assume that there’s life. Not for the existence of life directly</p>
<p>C)There refers to the laboratories which is false.</p>
<p>D)Seems awkward to me in comparison with the original sentence.
Wood5440’s assumption looks good:“The presence of living things doesn’t ‘indicate’ life; it IS life.”</p>
<p>Sorry if there’s mistakes, I’m an international</p>
<p>If the first one is correct you don’t need to worry about replacing it with the other ones. </p>
<p>The first one is correct because on Mars, which is what I assume this is referring to, the lander was looking for evidence that living things had once existed on Mars, not that living things currently exist or were in the sample. The other three answers ask different questions.</p>
<p>^ I don’t think the test taker is required to know the context. Also, the correct answer “indications of the presence of living things” does not suggest that testing is for life in the past.</p>
<p>I do not like this choice the way it is stated…</p>
