Answer:
a. larger pipe diameters
Explanation:
This is the factor that allows pipelines to increase their capacity and move an increased amount of tonnage. When we increase the diameter of a pipe, this allows a larger volume of material (water, oil, etc.) to move through it. This means that we are able to move a larger volume (tonnage) of material in a shorter amount of time. This increases the efficiency of the pipelines in a very significant way.

The correct answer would be the Renaissance, but since that’s not there I’d say the closest would be A.

The following are some everyday objects that play with expected proportional relationships or were created on an unusual scale:
Purchase of an Object vs the Number of Objects Purchased, earning of a Worker per Day, Petrol consumption and distance travelled, Shadow and Height of Objects, Age and height of a person, and Temperature and Flame.
Proportions in daily life is further exemplified in the scenario of architecture. It is unusual to see big and rising buildings, such as skyscrapers, the proportions of most buildings and homes reflect the functional use of the space. Other buildings take on unusual proportions. 
<h3>How proportions are used in daily life?</h3>
Ratios in recipes make it easy to increase or decrease as the case may be. Human food is balanced when it is rationalised on certain ration. To calculate how much is needed when increasing or decreasing, proportions are used. For example, if a 2 spoon of salt is needed to cook two cups of rice, then 4cups of water will be needed.
Therefore, the correct answer is as given above
