Sentence Restatement Question

Hi Irmak, let's solve this together. We need to find the option that is closest in meaning to the sentence: 'Since flu is an infectious disease, it depends entirely on human hosts to carry and spread it.'

Let's break this sentence down. It has two main parts connected by a cause-and-effect relationship.

First, let's analyze 'depends entirely'. If something depends entirely on another, it means that the other thing is absolutely essential. There is no other way.

Second, let's look at the word 'Since'. This expresses a cause, which we can easily restate using the coordinating conjunction 'so'.

Now, let's look at Option A: 'Flu is an infectious disease, so human hosts are essential for its carriage and spread.' Let's compare this with our breakdown.

As we can see, 'Flu is an infectious disease, so' perfectly matches 'Since flu is an infectious disease'. And 'human hosts are essential for its carriage and spread' perfectly matches 'it depends entirely on human hosts to carry and spread it'.
