阅读下面短文，掌握其大意，然后从下列各题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

We are not 13 of the usual smell of our own house but we 14 new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15 for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.
