<p>In the (early days) of steam locomotive, (compassionate) engineers would sometimes (have thrown) coal overboard (in poor) neighborhoods. (no error)</p>
<p>why is the answer c? its makes COMPLETE sense to me. </p>
<p>the survey (showed that) most shoppers who drive prefer the mall (more than) downtown stores (simply because) finding parking is (less difficult) at the mall. (no error)</p>
<p>answer: b. why?</p>
<p>observation of diverse animal species (show that) the (most successful) in the struggle are (those which) are most (adaptable to) changes in their world. </p>
<p>answer: A. Why? really doesnt make sense.</p>
<p>All the errors make complete sense …</p>
<p>The first one - ‘have thrown’’ The sentence is about the early days of steam locomotive ,so it refers to the past.Have shown is clearly a present perfect construction .It should be either ‘‘threw’’ or ‘‘had thrown’’</p>
<p>The second one - ‘‘more than’’’ You prefer sth TO sth ,not sth MORE than sth .</p>
<p>The thrid one - ‘’ show that ‘’ .This is probably the easiest .Observation is singular ,so it should be ‘‘shows that’’ ‘‘Animal species’’ are plural ,but the ‘‘show’’ refers to the ‘‘observation’’</p>
<p>thanks a lot “man” your are like the ultimate time deamon (Utd)</p>
<p>Wouldn’t the first one be “throw” rather than “threw” or even “had thrown”?</p>
<p>Doesn’t the “in the early days,” bring you back in time?</p>
<p>Yes,you are right .
Would already bring us back to the past so it should be just ‘‘throw’’</p>
<p>yeah, THAT makes sense. ok, now i am at peace</p>
