Consultant: you're welcome. as a first step, our team analyzed the other potential primary contenders. the reality is that with such a strong field, it is going to be difficult to gain the of votes necessary to avoid a runoff—unless you want to go negative from the start. and our opposition research team found plenty of ammunition to do just that.

A.Majority

Explanation:

...it is going to be difficult to gain the Majority of votes necessary to avoid a runoff.

The consultant here seems to be referring to a Runoff type of election where there are two rounds to voting. In this type of election, when no contender gets over 50% of the votes which is considered a Majority, the election goes to a second round with the highest 2 contenders or in some cases the contenders past a certain threshold then contending amongst themselves.

The Consultant is telling the candidate that the other candidates are quite strong so them getting the Majority vote required to avoid a second round will be tough.  

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
