Locally Arc-Connected Space is not necessarily Arc-Connected

Theorem
Let $T = \left({S, \tau}\right)$ be a topological space which is locally arc-connected.

Then it is not necessarily the case that $T$ is also arc-connected.

Proof
Let $T := \left({\R, \tau_d}\right)$ be the real number line $\R$ under the usual (Euclidean) topology $\tau_d$.

Let $a, b, c \in \R$ where $a < b < c$.

Let $A$ be the union of the two open intervals:
 * $A := \left({a \,.\,.\, b}\right) \cup \left({b \,.\,.\, c}\right)$

Let $T' := \left({A, \tau_A}\right)$ be the subspace composed of $A$ with the subspace topology induced on $\tau_d$ by $A$.

From Union of Adjacent Open Intervals is Locally Arc-Connected, $T'$ is a locally arc-connected space.

From Union of Adjacent Open Intervals is not Arc-Connected, $T$ is not a arc-connected space.

Hence the result.
