Answer

Brief Explanations:

  1. The word "difficult" often implies a challenge. "Solving the puzzle was challenging" has a similar connotation.
  2. The sentence "Velcro was inspired by tiny burrs sticking to a dog's fur" has one independent clause and no dependent clauses, so it is a simple sentence.
  3. Option b combines the two sentences with "and" in a simple and correct way.
  4. A compound sentence has two independent clauses joined by a coordinating conjunction. "Sticky notes are useful, and people use them around the world" fits this.
  5. A complex sentence has one independent and one or more dependent clauses. "Simple inventions matter because they make life easier" has a dependent - clause "because they make life easier" and an independent clause "Simple inventions matter".
  6. A compound - complex sentence has two or more independent clauses and at least one dependent clause. The given options do not have a correct compound - complex sentence example.
