Official Explanation
1. According to the passage, why has ECT been viewed negatively by the public?
Difficulty Level: 600
Explanation
(A) Though ECT is effective in many cases, the medical community is not certain exactly how it works.
The passage states both that ECT can be effective and that the exact mechanism by which it works is unknown. Neither of these, however, is cited by the passage as a reason that the public has viewed ECT negatively. (True but not right)
(B) Cultural depictions of ECT implied that the therapy infringed upon the lawful rights of those receiving the treatment.
CORRECT. The last sentence of the second paragraph says that examples…documented in books and movies…portrayed ECT as… violative of patient's legal rights.
(C) Effective use of ECT requires exposure to concerning medications, such as muscle relaxants and anesthesia.
The passage does state that ECT now uses muscle relaxants and anesthesia, but the passage does not call these medications concerning. If anything, the passage considers these positive advances, as the patient is asleep and fully unaware. (One word off)
(D) ECT does not benefit individuals with anxiety disorders.
The passage does not mention individuals with anxiety disorders. (Out of scope)
(E) ECT cannot be performed without subsequent loss of memory in the patient.
The last paragraph does mention that ECT can result in memory loss, but does not say that this side effect is always present. (Nor does the passage mention public conception with respect to memory loss.) (Extreme)
2. Which of the following can be inferred about the way in which the modern form of ECT works?
Difficulty Level: 700
Explanation
(A) Greater amounts of the neurotransmitters serotonin, norepinephrine, and dopamine seem to reduce symptoms of depression.
The third paragraph does talk about these neurotransmitters. Some people might think this is plausible in the real world, but be careful—you have to find proof in the passage. The third paragraph says only that repeated applications of ECT affect these neurotransmitters. It does not indicate what effect these neurotransmitters have on depression. (Out of scope)
(B) ECT cannot be used prior to attempting psychotherapy or medication.
Whenever you see an extreme word, check whether the passage justifies the usage. In this case, the third paragraph does not justify the use of the word cannot; it implies only that those other therapies are tried first at least some of the time. (Extreme)
(C) Succinylcholine completely immobilizes the patient's body.
The third paragraph states that succinylcholine renders muscle contractions practically nonexistent. The qualifier practically means the muscle contractions are almost gone, but not entirely. The word completely, then, is too extreme. (Extreme)
(D) ECT generally works faster than antidepressants.
CORRECT. The third paragraph states that ECT may also be considered when there is an imminent risk of suicide, since antidepressants often take several weeks to work effectively. If ECT is used when there is an imminent, or immediate, risk, because antidepressants take a while to work, then ECT must generally work more quickly than antidepressants.
(E) One ECT treatment is often sufficient to reduce symptoms of depression significantly.
The passage does not mention the number of treatments necessary to reduce symptoms significantly. At one point, it does mention repeated applications so, if anything, it appears that more than one treatment might be typical. (Out of scope)
3. The author mentions amnesia as a possible side effect of severe depression in order to
Difficulty Level: 600
Explanation
(A) acknowledge one of the possible negative side effects associated with ECT
The passage does talk about many negative side effects associated with ECT, but the reference to amnesia is intended to introduce the idea that certain side effects actually might not be due to ECT. (Direct contradiction)
(B) emphasize the seriousness of severe depression as a debilitating disease
This choice sounds very tempting: in the real world, amnesia is a very serious issue and severe depression is a debilitating disease. However, depression is mentioned only as a possible alternative cause; the passage does not state that the amnesia is definitely a result of the depression. (True but not right)
(C) introduce a possible alternative cause for short-term memory loss reported by some patients
CORRECT. The first half of the sentence brings up patient reports of memory loss due to ECT; the second half indicates that some doctors think this memory loss might actually be due to amnesia from depression.
(D) draw a connection between brain cell death and short-term memory loss
The fourth paragraph mentions both brain cell death and short-term memory loss. The passage does not connect the two ideas, however. In fact, it says that reports of brain cell death have been refuted, though memory loss is still in evidence. (Mix-up)
(E) refute claims that ECT is responsible for any form of amnesia in patients
The sentence does offer a possible alternative cause, but ECT is not definitively ruled out as one possible cause. (Extreme)
4. Each of the following is cited in the passage as a current or historical criticism of electroconvulsive therapy EXCEPT
Difficulty Level: 750
Explanation
(A) ECT may cause the death of brain cells and memory loss.
True. The fourth paragraph mentions that very old research showed brain cell death (even though that research has been refuted today) and that memory loss is an ongoing concern.
(B) In certain cases, ECT was portrayed as a means to punish individuals.
True. A Line indicates that ECT was portrayed as punitive.
(C) ECT had the potential to be used in inappropriate situations.
True. Tricky! Line 26 indicates that ECT was portrayed as overused. If a treatment is overused, then at least some of those uses shouldn't be happening, or are inappropriate.
(D) Early forms of ECT did not adequately protect patients from secondary harm brought on by the treatment.
True. Lines indicate that early forms of ECT often led to compression fractures of the spine or damage to the teeth.
(E) Repeated applications of ECT affect several neurotransmitters in the brain.
CORRECT. False. Lines 45–47 do mention that ECT affects neurotransmitters, but this information is not presented as a criticism of ECT. Rather, it is presented as a partial means of understanding how ECT works.
