Urban planners would most likely consult what when planning for the future of the city
Studentka2010 [4]

Answer: D. demographers

Explanation:

When planning for the future of a city, the urban planners need to ensure that the city is able to afford its current and future residents with the facilities needed to provide them with the maximum welfare possible.

To do this the urban planners should reach out to demographers. Demographers study human populations with a view to analyse and ascertain various characteristics such as size, composition, how they are distributed within a geopolitical zone and most importantly, how they will change overtime.

For urban planners to plan for a city that will take care of future residents as well, they would need to know how the kind of future residents they are planning for and this is when they will turn to demographers whose job it is to study and possibly predict future population.

In which country is it said that finding a spider web on christmas morning brings good luck
andreyandreev [35.5K]

Answer:

Ukraine and Germany

Explanation:

Spiders may seem like a more specific Halloween ornament, but eight-legged creatures actually play an important role in other parties. We have discovered the tradition of "Christmas spiders."

It is based on a European folk tale that has been attributed to several countries, often Ukraine and Germany. In a version of the Christmas spider story, a widowed mother and her children were too poor to decorate their Christmas tree, and friendly spiders wove elaborate nets on a fir tree. When the family woke up on Christmas morning, they opened the curtains and sunlight illuminated the cobwebs, turning them into silver and gold (sometimes it is said to be the origin of the garlands). The family had good fortune thereafter. Other versions affirm that it was Santa Claus or Jesus himself who transformed the networks so that they did not bother the mother.

It is likely that the legend is related to the idea that spiders give good luck. Whatever the real reason, according to various sources, Ukrainians decorate their Christmas trees with spider-shaped ornaments (often made of precious stones) to this day
