	Giant Molecular Clouds (GMCs) as Cluster Progenitors
	How do Stars Ordinarily Form in GMCs? Inefficiently At Sluggish Rates set by Ambipolar Diffusion Not as Bound Clusters (because e < < 50%)
	How Can the Bombs (i.e., GMCs) be Ignited During A Galaxy-Galaxy Interaction? Cloud-cloud Collisions? (an old-time favorite) Environmental Over-Pressure (Jog and Solomon 1992) Our Proposed New Ignition Mechanism
