  While galaxy clusters are dominated by quiescent galaxies at local, they show
a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here, we
present the discovery of two galaxy clusters at $z \sim 0.95$ with contrasting
QFs despite having similar masses (log ($M_{200}/M_{\odot}$)$ \sim 14$) and
spectra and redshifts of 29 galaxies in these clusters and 76 galaxies in the
surrounding area. The clusters are found in the Ultra Deep Survey (UDS) field
and confirmed through multi-object spectroscopic (MOS) observation using the
Inamori Magellan Areal Camera and Spectrograph (IMACS) on the Magellan
telescope. The two clusters exhibit QFs of $0.094^{+0.11}_{-0.032}$ and
$0.38^{+0.14}_{-0.11}$, respectively. Analysis of large-scale structures (LSSs)
surrounding these clusters finds that properties of these clusters are
consistent with the anti-correlation trend between the QF and the extent of
surrounding LSS, found in Lee et al. (2019), which can be interpreted as a
result from the replenishment of young, star-forming galaxies keeps the QF low
when galaxy clusters are accompanied by rich surrounding environments.
