The resistors are arranged in a combination of series and parallel. Two resistors are in parallel, giving an equivalent resistance of 1.0 Ω. This is in series with the other three resistors, each 2.0 Ω, resulting in a total equivalent resistance of 1.0 Ω + 2.0 Ω + 2.0 Ω + 2.0 Ω = 7.0 Ω. However, the correct configuration should be checked with the figure to confirm the arrangement.
