First question: C
Second question: B

In the second question answer B states that streight lines represent part of the more complex structure of lines in which the "bird lines" are also the part of the more complex structure. Therefore, this statement "counters an objection that the crossing of the straight-line pattern over the bird figure shows that the two kinds of line pattern served unrelated purposes".

In Peru, ancient disturbances in the dark surface material of a desert show up as light-colored lines that are the width of a footpath and stretch for long distances. One group of lines branching out like rays from a single point crosses over curved lines that form a very large bird figure. Interpreting the lines in the desert as landing strips for spaceship-traveling aliens, an investigator argues that they could hardly have been Inca roads, asking, “What use to the Inca would have been closely spaced roads that ran parallel? That intersected in a sunburst pattern? That came abruptly to an end in the middle of an uninhabited plain.”

Can anyone explain what the premise says? I dont even get that. :oops:
What does the last part of the argument says?

The pattern discovered could have served 2 purposes:
1. Roads
2. Landing strips for spaceships

The investigator has the opinion that the second hypothesis (landing strips) is correct.

Premise for the above opinion: Closely spaced parallel roads abruptly ending in uninhabited land is useless as roads - hence they must have been landing strips.

Option C is correct.

OA added.
