1. ​​The passage suggests that which of the following was true of the honeybee colonies described in line 4-6?

(A) Their life expectancy, when free of disease, was shorter than that of European bee colonies in North America.
- not mentioned in the passage.
(B) They were not Africanized. - In the second sentence of the paragraph, we have "In parts of Europe, this mite is devastating honeybees and killing many colonies despite preventive measures by beekeepers." Further into the paragraph, we get to learn that Africanized bees are not affected by the parasite. Hence, we can reasonably infer that the European bees are not africanized. Hence, (B) is the right answer choice.

(C) Their life cycle did not accommodate the feeding habits of Varroa jacobsoni.
- not discussed in the passage.
(D) They responded well to measures to control Varroa jacobsoni. - not implied in the passage.
(E) They were managed using methods that were more modern than those employed in Brazil. - not mentioned in the passage.

2. The author cites all of the following as evidence that Africanized bees’ resistance to Varroa jacobsoni is superior to that of European bees EXCEPT:

(A) Fewer Varroa jacobsoni mites reproduce in Africanized bees
. - Towards the middle of the passage, we have "But fewer mites reproduce in Africanized bees than in European bees."
(B) Varroa jacobsoni is killing many bee colonies in Europe. - In the second sentence of this passage, we have "In parts of Europe, this mite is devastating honeybees and killing many colonies".
(C) Beekeepers in Brazil have not used preventive measures to protect their colonies. - In the third sentence of the passage, we have "But in Brazil Varroa jacobsoni has been present in Africanized bees since 1972 without the loss of a single colony, even though beekeepers there undertook no preventive measures."
(D) Brazilian bee colonies have endured Varroa jacobsoni since 1972.
- In the third sentence, we have "But in Brazil Varroa jacobsoni has been present in Africanized bees since 1972"
(E) At least some European bee colonies have been saved by preventive measures. - This is not implied anywhere in the passage. Hence, (E) is the right answer to this EXCEPT question.

3. According to the passage, research suggests that one possible reason the Africanized bees in Brazil have successfully resisted Varroa jacobsoni is that

(A) the life cycle of the Africanized bee may limit the Varroa jacobsoni mite’s opportunity to reach full development - Towards the end of the passage, we have "Some researchers point out that this resistance may be related to the Africanized worker bee’s shorter development period, which prevents some mites from reaching maturity." Hence, (A) is the right answer choice.

(B) the Africanized bees may have had an opportunity to develop a chemical resistance to Varroa jacobsoni - not implied by the passage.
(C) the location of bee colonies in Brazil may provide a natural deterrent to Varroa jacobsoni
- not implied by the passage.
(D) Varroa jacobsoni may be relatively new to Brazil and may not have had time to become widespread - false. since we already know that the virus has been prevalent in Brazil since 1972.
(E) beekeepers may have developed effective control techniques for Varroa jacobsoni
- the passage mentions that bookkeepers have not implemented any control techniques.

4. ​​​​The author’s argument regarding the resistance of Africanized bees to Varroa jacobsoni would be most weakened if which of the following were true?

(A) The bees in Brazil were resistant before being Africanized. - if this were true, then the passage cannot support the assertion that the resistance of the Africanized bees in Brazil can be attributed to the shorter development period, which prevents some mites from reaching maturity. Since this assertion can no longer be supported, the author's argument will be weakened. Hence, (A) is the right answer choice.

(B) The number of bee colonies in North American increased dramatically whereas the number in Brazil remained unchanged.
- the passage is not concerned with the ''number of bee colonies''.
(C) Mites found in European bees reproduce at a faster rate than mites of identical species found in the bees in Brazil.
- irrelevant to the passage.
(D) Africanized bees retain many of the characteristics of European bees.
- the passage does not imply this in any way
(E) Bee colonies in Europe continue to produce greater quantities of honey than do those in Brazil.- the passage does not make any assertion regarding the ''quantities of honey''.

Re: One advantage of breeding African bees with other bee types [#permalink]
I have a query.
So do we need to consider it as a line in the paragraph or we have to consider it as a sentence (ie sentence 4-6)

Hi mayurmb,

Lines 4-6 are the lines of the paragragh and not sentences.

Lines in concern are: "In parts of Europe, this mite is devastating honeybees and killing many colonies despite preventive measures by beekeepers".

Hope This Helps.
Thanks.

1. ​​The passage suggests that which of the following was true of the honeybee colonies described in line 4-6?

(A) Their life expectancy, when free of disease, was shorter than that of European bee colonies in North America. this line is talking about European bees only, hence, irrelevant
(B) They were not Africanized. CORRECT - The European bees were not Africanised, hence, the devastation caused by mites
(C) Their life cycle did not accommodate the feeding habits of Varroa jacobsoni. Irrelevant
(D) They responded well to measures to control Varroa jacobsoni. Irrelevant
(E) They were managed using methods that were more modern than those employed in Brazil.Irrelevant - we are talking about the devastation caused to bees in Europe.

Lines 4-6: In parts of Europe, this mite is devastating honeybees and killing many colonies despite preventive measures by beekeepers.

2. The author cites all of the following as evidence that Africanized bees’ resistance to Varroa jacobsoni is superior to that of European bees EXCEPT:

(A) Fewer Varroa jacobsoni mites reproduce in Africanized bees.But fewer mites reproduce in Africanized bees than in European bees.
(B) Varroa jacobsoni is killing many bee colonies in Europe.In parts of Europe, this mite is devastating honeybees and killing many colonies despite preventive measures by beekeepers.
(C) Beekeepers in Brazil have not used preventive measures to protect their colonies.beekeepers there undertook no preventive measures.
(D) Brazilian bee colonies have endured Varroa jacobsoni since 1972. In Brazil, Varroa jacobsoni has been present in Africanized bees since 1972 without the loss of a single colony
(E) At least some European bee colonies have been saved by preventive measures. This has been nowhere mentioned in the passage.

4. ​​​​The author’s argument regarding the resistance of Africanized bees to Varroa jacobsoni would be most weakened if which of the following were true?

(A) The bees in Brazil were resistant before being Africanized. If this is true, then, Africanisation did not have any impact on the bees.
(B) The number of bee colonies in North American increased dramatically whereas the number in Brazil remained unchanged. Irrelevant
(C) Mites found in European bees reproduce at a faster rate than mites of identical species found in the bees in Brazil. This can be due to Africanisation, hence, this will strengthen.
(D) Africanized bees retain many of the characteristics of European bees. Does not have an impact.
(E) Bee colonies in Europe continue to produce greater quantities of honey than do those in Brazil. Irrelevant
