The cost of a single dose of praziquantel has been reduced to $1.40 for adults and 74 cents for children, who make up 60 to 70 percent of the victims of the disease. Only four years ago a single adult dose cost about $4.20. The single dose appears to offer two to three years' defense against reinfection by the disease, which attacks such organs as the intestines and liver. Although the disease is not often fatal, it is so debilitating that it has become an economic drain on many underdeveloped countries.

Hi all,
Schistosomiasis, a disease caused by a parasitic worm, is prevalent in hot, humid climates, and it has become more widespread as irrigation projects have enlarged the habitat of the freshwater snails that are the parasite's hosts for part of its life cycle.
Meaning: • Schistosomiasis is a disease that is caused by a parasitic worm. • It is prevalent in places with hot and humid climate. • The disease has become more widespread with the increase in irrigation projects. • These projects have enlarged the habitat of the freshwater snails that play the host of the parasite for a part of its life cycle.
Error Analysis: • Subject “that” that stands for “the freshwater snails” agrees in number and makes sense with the verb “are”. No SV pair error. • This sentence is providing general facts about the disease and its cause. Hence simple present tense “are“ is correct. • “that” clause correctly modifies “the freshwater snails” giving information that these snails become host to the parasite for some part in its life. • There are no pronoun, no parallelism, no idiom and no meaning error errors.
Answer Choice Analysis: A. the freshwater snails that are the parasite's hosts for part of its life cycle: Correct as is.
B. the freshwater snails that are the parasite's hosts in part of their life cycle: Incorrect. Reference of pronoun “their” distorts the intended meaning of the sentence. Plural “their” now refers to “the freshwater snails” meaning that they are host to the parasite in part of snails’ life cycle and not in part of the parasite’s life cycle. This is not the intended meaning of the sentence.
C. freshwater snails which become the parasite's hosts for part of its life cycles: Incorrect. Plural “life cycles” is incorrect because a singular “parasite” can have only one life cycle and not multiple life cycles.
D. freshwater snails which become the hosts of the parasite during the parasite's life cycle: Incorrect. Repetition of “parasite’s” instead of a pronoun makes this choice wordier.
E. parasite's hosts, freshwater snails which become their hostsduring their life cycles: Incorrect. Same pronoun reference error as in B.
Take-Away 1. The pronoun must agree in number with its antecedent. 2. Be vary of the choices that distort he intended meaning of the sentence.
Hope this helps. Thanks. Shraddha

Economic means relating to the economy; economical means inexpensive’ If something is an inexpensive drain, why will the disease be a drain on the economy? So economical is incongruous in this context.

Shraddha,
haven't we learnt that a pronoun cannot refer to a possessive noun. Unless its here is referring to worm.?
Also Its mentioned by one of the members(supposedly expert) that
" MGMAT( in a reversal form its earlier rigid stand perhaps) says that the issue of possessive poison is not worth worrying about, since there has been hardly any case that has been rejected on the score of the possessive pronoun’s antecedence in the realm of GMAT.
The take away of possessive pronoun custom is;
1. A possessive pronoun can stand for a possessive noun 2. A possessive pronoun can stand for a non- possessive noun 3. A non possessive pronoun can stand for a non- possessive noun. 4. The only case where it can‘t be accepted is when a Non- possessive is used to stand for a possessive noun "
Please comment as I have a concept that a pronoun cannot refer to a noun in possessive form.

Dear ygdrasil24,
Your understanding is correct.
However, note that "its" is the possessive form of the pronoun "it".
Usually for nouns, we add an apostrophe and an "s" to indicate possessive form. ("lion's", "builder's" etc.)
However, it's on the other hand is the short form for "it is". The possessive form of "it" is "its"
As you know, the possessive form of a pronoun can refer to the possessive form of a noun.
In the above mentioned sentence "its" (possessive pronoun) is referring to "parasite's" (possessive noun).

Why C is wrong?
c is wrong because c is not idiomatic. we do not have inverted pattern like this. end of story. e is wrong because "it" in this pattern of e has no clear reference. moreover, "economical" mean saving and is wrong. b and D have no "that" and become wrong structrurally.

We want to comment on schistosomiasis, therefor we need to introduce our answer with "it is" because "it is" refers to that strange word. C/D/E, gone. B omits "that" and it uses "economical" incorrectly - By the way, so do D and E - so that leaves us with A, which correctly uses it, that and economic.

C. so debilitating is it as to become an economic
C is an inverted sentence:
so debilitating (not a subject) is (verb) it (subject found) as to become an economic blah blah blah...
Re arrange : it is so debilitating as to become an economic ... Correct Idiom is : so (adjective) that (clause)
Thus Option A is right.

Analysis of the original sentence -
Meaning - S is not fat but S is so debilitating that it has hurt developing countries
• Although (DC marker) schistosomiasis (subject) is (verb) not often (adverb) fatal (adjective) ---- (DC) • It (subject – pronoun refers back to subject of DC) is (verb) so debilitating (adjective??) ----IC • that it (subject – pronoun) has become (verb) an economic drain on many developing countries.---- DC
POE -
A) No error b) it is of such debilitation, it has become an economical such x that y - that is missing C> though it sound very awkward but cant pin point the exact error. Is SO X AS TO BECOME Y correct. If so what could be X and Y. If X has to be an adjective then there is no IC in option C. D> such is its debilitation, it becomes an economical - Meaning issue...when one says its debilitation - does that mean S is in a debilitated state E> there is so much debilitation that it has become an economical - Change in meaning. Option doesn't clearly states that S causes debilitation

Dear Student,
Thank you for your post.
In your meaning analysis, you have correctly identified the clauses and different subject-verb pairs in the sentence. Also, you have rightly categorized “debilitating” as an adjective here.
As regards the analysis given by you in the POE section, please find below my comments on the same:
1. Choice A: It is definitely the correct choice. 2. Choice B: You have correctly recognized the shift in meaning that the word “economical” creates in choice B. The word economic means pertaining to the economy. However, the word economical means not wasteful. Clearly, we need the word “economic” here. Also, you are right- “that” is required before the dependent clause. 3. Choice C: So X as to Y is not the correct idiom. This may be the reason that choice C sounds incorrect to you . 4. Choice D: You are on to something very important here. Because of the way the word “debilitation” has been used here, it seems to refer to the state the disease itself is in rather than the effect it has on something else. Clearly, this distorts the intended meaning of the author. Choice D is in fact incorrect for almost the same reasons as choice B. 5. Choice E: Absolutely spot on!
Although, shistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many devloping countries
(A) it is so debilitating that it has become an economic drain (B) it is of such debilition, it has become an economical (C) so debilitating is it as to become an economic (D) such is its debilitation, it becomes an economical (E) there is so much debilitaiton that it has become an economical.

Check for the non underlined part of the sentence (Which is always correct!, Here it is Developing) , ing verb form - Developing, look for the options which have ing+verb (Here it is - debilitating /debilition) in underlined options (a, b, c, d, e) , It must match (ing+verb == ing+verb) , So clearly options (B, D and E) are OUT. Out of options A and C, look at option C - Wordier sentence and not parallel. So, Options A is the correct answer.

Although, shistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many developing countries
(A) it is so debilitating that it has become an economic drain - Correct (B) it is of such debilition, it has become an economical - Noun “debilitation” is not similar to adjective “debilitating” in meaning. While the noun means “weakness”, the adjective means “weakening”. Similarly, noun “economical” is not the same as adjective “economic”. The noun means easy on pocket or lesser in price while the adjective means pertaining to economy. (C) so debilitating is it as to become an economic - idiom issue - “so X as to Y” is incorrect (D) such is its debilitation, it becomes an economical - This choice repeats the “debilitation” and economical” expression errors of Choice B (E) there is so much debilitaiton that it has become an economical. - same as B
Answer A

Hi x2suresh,
Thank you for your question. Here is how I tackled this question, starting with a quick glance over each answer to find obvious differences.
The first thing I noticed is a common vocabulary issue that shows up in GMAT questions: economic vs. economical. They mean two different things, so let's decide which one we should use:
Economic = dealing with the economy Economical = being thrifty; spending less money
Based on their definitions and the original meaning, we should only keep answers that use "economic" because the sentence is talking about the economy, not thriftiness. Therefore, we can rule out answers B, D, & E.
Now we're left with answers A & C. Let's look at what's different about each:
(A) it is so debilitating that it has become an economic drain This is the CORRECT answer because it uses the word "economic" correctly, and it uses parallel structure.
(C) so debilitating is it as to become an economic This one is INCORRECT because this is not the proper idiomatic structure to show cause & effect, and it also sounds incredibly awkward.

Hello, If i am not wrong we do us the phrase "so X as to Y" in some cases. correct me if i am wrong
Example: 1)Often major economic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in the financial markets.
2)The category 1 to 5 rating known as the Saffir-Simpson Hurricane Scale provides an estimate of a hurricane’s potential of destroying or damaging property, and is primarily determined from wind speed; a category 5 storm has wind speeds so high as to blow away small buildings, completely destroy mobile homes, and cause severe window and door damage.
