Probably incorrect answer on Quiz (Physical Layers for Ethernet)

Hi,

Question in quiz is “Which of the following is an advantage of 10BaseT?”.
Correct answer according quiz is “Maximum distance between stations was reduced compared to Ethernet”.
Answer which looks correct for me: “It has fewer points of failure than 10Base5, 10Base2, and 10BaseF and so is more reliable”.

I see in lesson text “The cable is a weak point in 10Base2 and 10Base5 networks. Any physical damage on the cable broke the entire network and when such a failure occurred, the network administrator had to manually check the entire cable to detect where it was damaged. With 10BaseT, when one twisted pair is damaged, only the device connected to this twisted pair is affected and this does not affect the other devices.”
Doesn’t it mean that 10BaseT is more reliable?
