b) Phonemic restoration

c) Word boundary effects

d) The importance of visual cues in speech processing

When we communicate with one another we are usually using different visual cues during our speech to help the other person understand and get a better understanding of what we are saying and by our gestures we also increase the interest of our audience in what we are saying.

In this example, Heather notes that it's easier to understand her sister's speech on Skype than on telephone. It is clear that when we're on the telephone we really don't see the person or their cues and gestures, and we do see those when we are in Skype. These cues help us understand the speech better because these physical cues help us guide us through the speech. Therefore, the phenomenon may be an illustration of d) The importance of visual cues in speech processing

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
