ACT Challenge Question 18: English Topic Sentences

Magoosh ACT Challenge Question


Topic sentence questions on the ACT English test are sometimes a piece of cake…and sometimes they aren’t. Here’s a tougher one below! Can you figure out what the ACT is looking for you to do? Post your answer and explanation in the comments, and we will share the answer and solution later this week!

Fallingwater, one of the most famous examples of organic architecture, was designed by Frank Lloyd Wright. The family had given him free reign to construct their house on any location on their extensive land. Wright made the bold decision to place the house over a waterfall on the site. He then designed a house with many horizontal stones the same color as the rocks found in the surrounding area. This design structure allowed the house to blend in with its surroundings, looking almost as if it were made by nature rather than a human.

Which of the following true statements would best introduce the paragraph?

  2. One of the most famous examples of organic architecture is Frank Lloyd Wright’s Fallingwater, a house he built for a Pennsylvanian family.
  3. Fallingwater is a famous example of organic architecture built for a Pennsylvanian family.
  4. Frank Lloyd Wright designed one of the most famous examples of organic architecture in 1964.
