Question

use the drawing below to answer the question.
model sailboat race
which question would the model sailboat race most likely help answer?
(a) which materials are best for building a sailboat?
(b) what is the best shape for a sail on a large sailboat?
(c) how do different sail shapes affect a sailboat’s movement?
(d) how does the material a sailboat is made of effect its speed?

Explanation:

The model shows sailboats with different sail shapes being tested with a fan (simulating wind). This setup is designed to observe how the different sail shapes impact how the sailboats move. Option a and d focus on materials, which are not varied here. Option b asks about the "best shape for a large sailboat," but the model tests the effect of shape on movement, not just identifying the single best shape for a large boat. Option c directly matches the variable (different sail shapes) and the outcome (sailboat movement) being tested.

Answer:

c. How do different sail shapes affect a sailboat's movement?
