Select the BEST answer. The MAC only has Party leaders who are not in the military as its chair and vice-chairs. No military leader has been allowed onto the SC-PB for several decades. The General Secretary of the CCP has been the Chair of the MAC since the early 1990s and has been able to promote his own people onto the MAC.
A shot of espresso is considered to be one (fluid) ounce, while a double shot is two (fluid) ounces. A fluid ounce is 30 mL (as opposed to an ounce by weight being 28 g). This volume refers to the espresso shot volume (water) that gets passed through the espresso. The weight of the coffee required for a single shot is typically 7 grams for a single shot, and 14 grams for a double shot.
But does it have to? The basics: a traditional espresso shot usually involves approximately 18 to 20 grams of espresso, with water extracted through it at high pressure to yield around 30 grams of liquid. Your local fancy-pants shop may well draw you a shorter shot, i.e. one with even less volume.
