Final answer:
Among the listed aircraft, the large commercial jetliners Boeing 747 and Airbus A380 are likely to have 2 galleys on board due to their high passenger capacity, as opposed to smaller aircraft like the Embraer E195 or the Cessna 172.
Step-by-step explanation:
In the world of aviation, aircraft sizes and configurations can greatly vary. However, considering the aircraft listed in the question: 1) Boeing 747, 2) Airbus A380, 3) Embraer E195, and 4) Cessna 172, only the Boeing 747 and Airbus A380 are likely to have 2 galleys on board.
These types of aircraft are large commercial jetliners designed to accommodate a high volume of passengers. For example, the Airbus A380 is the largest commercial jetliner in the world, able to carry up to 850 passengers in its two-deck fuselage.
On the other hand, smaller aircraft such as the Embraer E195 or the Cessna 172 would not require multiple galleys due to their comparatively limited passenger capacity.
