Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.
answer is D
My answer is A, free for discussion.
小王老师说,there be 出现……基本错……
我也觉得D比较好 不能of that 只能 of which所以E可以排除
sorry, 你的理由我不认同。
A中and that阐述并列,就很好。
其次,D中interfering with pacemakers做什么?
说there be一定错,已经被证明是没有实际推广价值的。
嗯,看着看着
确实觉得C不对
但是前面我还是觉得there be 不简洁
同意你,A吧
A选项确实太罗嗦,暂且不考虑there be的问题,D的说法更符合规范:恢复之后便可看出200000 type of which exist worldwide,A读起来挺奇怪。interfering with pacemakers这句话是修饰exist的,也就是修饰magnetic fields的.这里没有对称我认为是合理的,因为根据逻辑意思,and this interaction can bring on ....这句话不是announce的内容,而是解释interaction的,所以没办法和前面并列.
我想把这句话翻译出来就更清楚了
研究人员声明:由厂商制造的安全监视系统所放射出的磁场当中200,000种磁场都在全世界范围内存在,并干扰脉冲设备,这种干扰可以带来心脏跳动消失或者不规律,恶心,呼吸不畅,头晕甚至晕厥

不敢苟同,这是句子碎片(framentation),因为它前面的只是一个同位语。
I support A.
D is absolutely wrong. “the magnetic fields emitted by one manufacturer’s security surveillance system interfering with pacemakers” – 谓语呢?
There be在OG里做正确答案的举不盛举啊. OG107, OG89, OG225. 不要相信老师的, 一切根据OG.
a
d 不能形成并列
.
同意A.
C中 interfering with pacemakers错, 这样一来根本就不是一个完整的句子
only part from nature.com, seems A has better chance:
<http://www.google.com/search?hl=en&q=%22security+surveillance+system%22+nature.com>
同意A.
C中 interfering with pacemakers错, 这样一来根本就不是一个完整的句子
agree with A.
remember i read from some note of one NN, he said "that....., and that...." is a preferable form of GMAT, compare with other choices don't have strong correct point. i think the answer should be A.
personel opinion
A 出现了数量词,使用of which there are搭配顺序不合理
多数正常表达方式 数量词+of which
B worldwide摆放位置不对
C 直接句尾+and,没有逗号隔开,错
D 纠正了A中“数量词位置”和“there出现”的错误,正确
E 限制性定语从句先行词用that,错
A
D中and前面不是一句完整的句子
只可能是A,原因很简单,Researchers have announced that
the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction
can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.
但A中的of which n. there are确实是个很awkward的结构,但却也只有A是对的。这又验证了我的猜想,虽然语法题没有提问句(像逻辑那样:which of the following...),而是直接对句子划线。但我认为,GWD的每一个语法题实际上是有隐含提问的,那就是:which of the following awkward sentence is correct?
