As though childhood is not sufficiently fraught with potential dangers,the Customer Safety Board has come forward with a report warning of yet another factor which could prove harm to one's children.According to this recent published report,over twenty-five thousand children per year are seriously injured in accidents involve shopping carts.Most of these accidents occur when the attending child attempts to climb down from the cart.Beacause most shopping carts lack of appropriiate safety harnesses of straps,the child may tumble from the cart, often sustaining life-threatened head injuries.In a small minority of case,due to a narrow wheelbase,the cart has actually tipped over,spilling the hapless child on the hard floor.The director of Emergency Aid at S1.Hope Hospital warns parents never to leave children unattended while shopping and further advised that parents should insist that store managers have safe straps or seats installed on all shopping carts

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

Alzheimer's disease impairs a person's ability to recall memories, both distant and as recent as a few hours before. Although there is not yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs. Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiments do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.

Which of the following could best replace the word "significantly"?

A. considerably    

B. knowingly        

C. suggestively      

D. tirelessly
