Please explain why A is incorrect for Q3?


This is a CR-type strengthen question, It asks to strengthen some particular part of the passage. In the first paragraph lines say that:

"Switzerland began to see heavy truck traffic taking a major toll on its delicate highway passes roads intended more for tourism than for commerce. The solution was a constructive one-figuratively and literally: Dig a tunnel".

Concentrate the conclusion of the above lines and starts eliminating the answer choices.

Option a cover one side but not the other it only considers the tourism but not the commerce's point of view. Although traffic passes by more for tourism purpose than it does for the commerce but ignoring commerce altogether is wrong, So option A only covers a portion of the conclusion which strengthen the sentence specifically discussed and is wrong.

Thank you

Hi Sajjad1994
think the answer to Q2 should be D (OA=C).
D. underscore the difficulty of this engineering achievement.

The underlined portion of the text explains this -
Adding to the challenge presented by the necessary length and depth of the tunnel, the Gotthard massif, the rock formation through which the builders had to drill, is a geological jigsaw puzzle of folded and refolded layers of rock.

The underlined portion pretty much says that this is an additional problem which the builders had to deal with.
