Answer» RIGHT choice is (b) False Explanation: Normally, for CASTING with a high area to VOLUME (A/V) ratio (for example, for a plate and a bar), usually more than one riser is REQUIRED. And for the low area to volume (A/V) ratio casting like cube and sphere, one central riser can be used to feed the entire casting. In such cases, the proper LOCATION of the riser is decided.
