Help pls Read the map. A map titled Physical Features of East Asia. A key shows Lowlands in green, Highlands in yellow, and mountains with brown triangles. Large areas of yellow span across northern China and Mongolia, west toward Europe, east toward the rivers. Green areas run along the eastern and southern coastline and most of India.

What physical feature had the greatest effect on China’s contact with other countries?

Vast, flat deserts made northward travel easier.
Extensive highlands made westward travel difficult.
River systems helped travel between north and south.
High, dangerous mountains blocked southward travel.

Extensive highlands makes westward travel difficult. I think, not sure.

Explanation:

the crusades are one of the most significant events in the history of europe and the middle east.   they were a series of religious wars carried out by christian crusaders from europe during the timeframe of the middle ages.   beginning in 1095 ce, the crusades saw european knights and noblemen travel to the middle east in an attempt to capture the holy land away from muslim people that had controlled the region for the previous centuries.   the term crusade means ‘cross’.   therefore, the europeans that became crusaders viewed themselves as ‘taking up the cross’.   in fact, many of the crusaders wore crosses on their clothing and armor as they made their pilgrimage to the holy land.

explanation:

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
