Astyle of architecture popular in western europe beginning in the 12th century was the style, which featured thin walls, pointed arches, flying buttresses, and stained glass windows.
a. doric
b. romanesque
c. ionic
d. gothic

The correct answer is D. Gothic. During the 12th Century, many churches were remodeled to let light in during sermons, so that they would be easier for churchgoers to see and understand. Before then, most churches were built in a Romanesque style, with small windows and arches. 

Hope this helps!

True

i believe the answer is  the similarity is that both are sacrifices which have the same purpose and sacrifice - jesus christ, but the difference is in offering of that sacrifice.

 

the similarity is that both are sacrifices which have the same purpose (repenting our sins) and sacrifice - jesus christ.  the difference is in the way of the offering that sacrifice. the sacrifice of jesus on the calvary is sacrifice of his actual living body and blood, but the sacrifice of the mass is the sacrifice of the jesus through bread (body) and blood (wine). in the sacrifice on calvary jesus was offered for us; while at mass he offers himself through us.
