Problem: Given the question: Question: "What is the English name of Rambla?"  Context: "The Rambla is an avenue that goes along the entire coastline of Montevideo. The literal meaning of the Spanish word rambla is "avenue" or "watercourse", but in the Americas it is mostly used as "coastal avenue", and since all the southern departments of Uruguay border either the Río de la Plata or the Atlantic Ocean, they all have ramblas as well. As an integral part of Montevidean identity, the Rambla has been included by Uruguay in the Indicative List of World Heritage sites, though it has not received this status. Previously, the entire Rambla was called Rambla Naciones Unidas ("United Nations"), but in recent times different names have been given to specific parts of it."  Answer:

Problem: Given the question: Question: "How might the molten zinc be applied?"  Context: "Zinc is more reactive than iron or steel and thus will attract almost all local oxidation until it completely corrodes away. A protective surface layer of oxide and carbonate (Zn5(OH)6(CO3)2) forms as the zinc corrodes. This protection lasts even after the zinc layer is scratched but degrades through time as the zinc corrodes away. The zinc is applied electrochemically or as molten zinc by hot-dip galvanizing or spraying. Galvanization is used on chain-link fencing, guard rails, suspension bridges, lightposts, metal roofs, heat exchangers, and car bodies."  Answer:
++++++++++++++++++++++++++++++++
The answer is:
spraying
