At uncontrolled intersections, vehicles traveling on a paved two-lane road must yield to vehicles traveling on
a. a divided road
b. a four-lane road
c. an unpaved two-lane road
d. both a and b are correct

The correct answer is D) Both A and B are correct.

At uncontrolled intersections, vehicles traveling on a paved two-lane road must yield to vehicles traveling on a divided road and a four-lane road.

This is how you act safely and allow the crossing of other vehicles properly. Uncontrolled intersections have some degree of risk. That is why you must pay attention to what happens on the two sides of the other street to prevent and avoid accidents. Don't forget to learn the meaning of the traffic light signs and the road signs in order to be a good driver.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
