Questions & Answers about daitairuuto to kousokusen o kuraberu.

Why is と used between 代替ルート and 高速船?

Here と means with in the sense of compare A with B.

A very common pattern is:

A と B を 比べる
= compare A and B / compare A with B

So in this sentence, 代替ルート and 高速船 are the two things being compared.

Why is there only one を even though there are two things being compared?

Because 代替ルート と 高速船 works together as one comparison set, and を marks that whole set as the object of 比べる.

So the structure is basically:

• 代替ルート と 高速船 = the two items
• を = marks them as the object
• 比べる = compare

This is normal Japanese grammar. You do not need を after both nouns.

Could this also be said as 代替ルートを高速船と比べる?

Yes. That is also grammatical, and it is a very useful comparison.

• 代替ルート と 高速船 を 比べる
  = compare the alternative route and the high-speed boat/ferry

• 代替ルート を 高速船 と 比べる
  = compare the alternative route to/with the high-speed boat/ferry

The meaning is very similar, but the second version can make 代替ルート feel a little more like the main thing being examined.

Why is the verb at the end?
