Incorrect. Parts = perfectly engineered, so car = perfectly engineered. Same flaw, as it's possible that the perfectly engineered parts are put together in an ineffective manner.

Correct. Argument or Facts:
Argument

Valid or Flawed:
Flawed

Question Type:
Bizarro Flawed Parallel Reasoning

Stimulus Summary:
Each particle of the universe is elegantly simple, so the universe is elegantly simple.

Answer Anticipation:
Jumping from an individual part of something to the whole? That's a Part vs. Whole jump (specifically from the part to the whole). It could be the case that all of those simple particles come together to form a ridiculously complex structure.

Answer Explanation:
Tricky! This answer is jumping from the parts to the whole, but it's not doing so invalidly. If each piece of the desk is metal, then the desk must also be made of metal. This is a rare example on the LSAT of a valid jump from the part to the whole.

Key Takeaway:
This question features an answer that does jump from a part to a whole, but it does so validly. This is extremely rare on the LSAT, so we wouldn't recommend being on the lookout for another example of this moving forward. Just know that certain qualities do jump from the whole to the part.

Incorrect. Bricks = rectangular, so wall = rectangular. You can build a wall of almost any shape out of rectangular brick, so this answer has the same flaw as the stimulus.

Incorrect. Piece = sturdy, so chair = sturdy. If the parts are poorly assembled, they could be sturdy while the chair is on the verge of falling apart.

Incorrect. Sentence = well-constructed, so novel = well-constructed. It's possible that each sentence is a masterpiece . . . but together they don't tell a story worth telling.
