Currently, the paramount problem in the field of biomaterials, the science of replacing diseased tissue with human-made implants, is control over the interface, or surface, between implanted biomaterials and living tissues. The physical properties of most tissues can be matched by careful selection of raw materials: metals, ceramics, or several varieties of polymer materials. Even the requirement that biomaterials processed from these materials be nontoxic to host tissue can be met by techniques derived from studying the reactions of tissue cultures to biomaterials or from short-term implants. But achieving necessary matches in physical properties across interfaces between living and non-living matter requires knowledge of which molecules control the bonding of cells to each other—an area that we have not yet explored thoroughly.  Although recent research has allowed us to stabilize the tissue-biomaterial interface by controlling either the chemical reactions or the microstructure of the biomaterial, our fundamental understanding of how implant devices adhere to tissues remains woefully incomplete.    1  
 A 
 1. According to the passage, the major problem currently facing scientists in the field of biomaterials is

(A) assessing and regulating the bonding between host tissue and implants
(B) controlling the transfer of potentially toxic materials across the interface of tissue and implant
(C) discovering new materials from which to construct implant devices
(D) deciding in what situations implants are needed
(E) determining the importance of short-term implants to long-term stability of tissue-implant interfaces

2  
 C 
 2. The passage suggests which of the following about the recent research ( Text in Blue )?

(A) It has solved one set of problems but has created another.
(B) It has concentrated on secondary concerns but has ignored primary concerns.
(C) It has improved practical applications of biomaterial technology without providing a complete theoretical explanation of that improvement.
(D) It has thoroughly investigated properties of biomaterials but has paid little attention to relevant characteristics of human tissue.
(E) It has provided considerable information on short-term implant technology but little on long-term implant technology.

(A) answer a theoretical question in the field of biomaterials
(B) discuss the current state of technology in the field of biomaterials
(C) resolve a research dispute in the field of biomaterial
(D) predict an ethical crisis for biomaterials researchers

Pls post OE for Q3

I believe I am the first one to reply here but please feel free to chime in in case i missed a crucial point.

This was a relatively simple passage maybe sub-600.

Here's my mind map & rationale.

Para1: Author discusses some paramount medical problem. Explains the reason for it and later says that recent research has helped in a part of the problem but some challenges still persist.

1. According to the passage, the major problem currently facing scientists in the field of biomaterials is

(A) assessing and regulating the bonding between host tissue and implants  Straightforward quote from line 3 & 4  
(B) controlling the transfer of potentially toxic materials across the interface of tissue and implant
(C) discovering new materials from which to construct implant devices
(D) deciding in what situations implants are needed
(E) determining the importance of short-term implants to long-term stability of tissue-implant interfaces

C 
 2. The passage suggests which of the following about the recent research ( Text in Blue )?

(A) It has solved one set of problems but has created another. The passage does not say that new research created new problems 
(B) It has concentrated on secondary concerns but has ignored primary concerns. Tempting. But from the highlighted text we don't know what's primary and what's secondary 
(C) It has improved practical applications of biomaterial technology without providing a complete theoretical explanation of that improvement. Seems correct. Because new research "stabilized the tissue-biomaterial interface" (improved practical applications), but our fundamentals still remain unclear (theoretical explanation)  
(D) It has thoroughly investigated properties of biomaterials but has paid little attention to relevant characteristics of human tissue.  Out of scope 
(E) It has provided considerable information on short-term implant technology but little on long-term implant technology. OOS

B 
 3. The author’s primary purpose is to

(A) answer a theoretical question in the field of biomaterials  180 degree. The passage even till the end is unable to answer the fundamental question 
(B) discuss the current state of technology in the field of biomaterials  Correct 
(C) resolve a research dispute in the field of biomaterial There is no dispute in the first place 
(D) predict an ethical crisis for biomaterials researchers OOS 
(E) suggest some practical benefits of biomaterial implants  OOS

Hello GDT

Unfortunately i don't have OE of this RC, As far as i know you have participated in RC Butler competition and i was not expecting such a question by you. Question #3 is very very easy and i would say it is not even a 500 level question and is rather a 400 level question.

(A)  answer a theoretical question  in the field of biomaterials.

No answer is given by the author, even none of the question is raised.

(B)  discuss the current state of technology  in the field of biomaterials

True

(C)  resolve a research dispute  in the field of biomaterial

The paragraph is very short one and one can easily say that nothing is resolved in it.

(D)  predict an ethical crisis  for biomaterials researchers

Prediction?? ethical crisis??

(E) suggest some  practical benefits  of biomaterial implants

Nothing is available as such in the passage

Answer: B
