The bridges in our town are highly unsafe for commuters because of low railings. The number of deaths, as a result of fall from a bridge, is reported to have increased many-fold. The deceased were mostly in the age group 18-24. The warning signs don’t clearly indicate the hazard. The management is, therefore, the one to be blamed for the deaths caused by fall from the bridge.

Which of the following, if true, would pose a serious doubt on the author’s conclusion?

Bridges have been a preferred location for committing suicides in the city.

The sidewalks of the bridge have become slippery for lack of regular cleaning but go unnoticed causing accidents.

Glow-in-the-dark signs and reflectors are dysfunctional and have not yet been replaced by the management.

Warning signs, if properly placed, help a lot in preventing accidents like falling off a bridge.

Since the accident rate is much higher in the case of youngsters, the possible reason could be over speeding.
