解释：

Solution

1. True. In some situations, an excess infusion of money into the economy doesn't further reduce interest rates or stimulate real activity due to an infinitely elastic money demand. This scenario is referred to as a liquidity trap, rendering monetary policy less effective.
2. False. The decline in private sector investments caused by increased government borrowing is termed the crowding out effect, which typically pertains to challenges in enacting fiscal policy.
3. False. The time delay in executing government spending decisions is known as the action lag. It's a challenge usually linked to fiscal policy where, for instance, initiating public infrastructure projects to boost employment might require considerable time to roll out.

Monetary Policy

正确。在某些情况下，由于货币需求具有无限弹性，向经济中过度注入货币不会进一步降低利率或刺激实际活动。这种情况被称为流动性陷阱，使货币政策的有效性降低。
错误。政府借贷增加导致的私营部门投资下降被称为挤出效应，这通常与制定财政政策方面的挑战有关。
错误。执行政府支出决策的时间延迟被称为行动滞后。这一挑战通常与财政政策有关，例如，启动公共基础设施项目以促进就业可能需要相当长的时间才能推出。
