Example Question #122 : How To Find Research Summary In Biology
Two scientists are examining the fragmented skeletal remains of an unidentified person. To begin work on identification, they must start by determining several characteristics about the individual, including sex. When determining sex, a measurement index can be used. Measurements can be taken from various points on the skeleton, such as the scapula or the femur, which then correspond to documented averages for different sexes, which vary with ancestry. In this individual of Latin American ancestry, the scapular breadth has measured 22.0cm, which is the only true sex-determining measurement that can be taken from these remains. In their reference books, the scientists find that this measurement in Latin American females ranges from 18.0-22.0cm and 22.0-24.0cm for Latin American males. Both scientists make a case using other supporting evidence as to which sex this unidentified individual may be.
Scientist 1
Sex can be clearly defined through context clues. Items found with the body and the way the body was found can both be used to determine the sex of the individual in cases such as this which lack other sex-determining measurements. The remains were found with small tennis shoes (size 8), which would generally be indicative of a female. The bag found with the body contained waterlogged copies of several popular magazines, as well as a broken cell phone, nail clippers, and a tube of lip balm. These items are generally more associated with items commonly carried by and used by female individuals rather than males. Because of abundant context clues, this individual can be determined to be female despite ambiguous measurements.
Scientist 2
Clues about the sex of the individual can come from multiple sources. Context clues, such as the items found with the body, can help. The small shoes and stereotypically female-associated objects found with the remains can give an indication that the person must likely have been female. Another way to help determine sex is through estimated overall stature of the person – men are generally larger and more robustly built than females of the same ancestry. A rough estimation of stature of this individual would indicate that they were about 5’10” tall and heavily muscled. While not impossible for a female, this is a build that is much more likely to belong to a male individual. Though the context clues seem to point toward a female, the stature of the individual strongly suggests male.
Based on the views of Scientist 1, if an individual was found with no objects, what might they conclude?
There is not enough evidence to determine sex based
The individual is likely female
The individual is likely male
Body measurements are very accurate and may be used to determine sex
There is not enough evidence to determine sex based
Scientist 1 relies mainly on context clues to determine sex, so if there were no context clues, they would not be able to determine the sex of the individual.

What other evidence might Scientist 2 look for to best support his/her claim?
Research on Latin American ancestry
Historical cases of female Asian individuals
Historical cases of Latin American male individuals
Information about the town where the individual was found
Historical cases of Latin American male individuals
Historical cases would be useful to compare this new but similar case to. The other information is not be relevant and would not support Scientist 2's claim.

How might Scientist 2 respond to Scientist 1’s methods?
Scientist 2 would say that Scientist 1 needs more information about Latin American religious practices
Scientist 2 would say that Scientist 1 needs more information about shoes
Scientist 2 would agree with Scientist 1’s methods
Scientist 2 would say that Scientist 1 needs more evidence than just one method can provide
Scientist 2 would say that Scientist 1 needs more evidence than just one method can provide
While the other objections might also be made, the fact that Scientist 1 only uses one source of proof would likely bother Scientist 2 (who uses multiple methods) the most.

If the scapular breadth was 23.0cm instead of 22.0cm, how might Scientist 1 respond?
They would no longer believe that context clues matter
They would use another method of determining sex in combination with context clues to check their answer
They would disagree with Scientist 2
They would not change their answer
They would use another method of determining sex in combination with context clues to check their answer
Because the measurement is more similar to males according to the given information in the problem, Scientist 1 would likely find something else to use as proof since the context clues indicate female instead of male.

Suppose the individual was eventually identified and proven to be female. Which methods would have proven most useful?
Height

Ancestry
Context clues
Context clues
Because the context clues pointed to the individual being a female and the rest of the information was ambiguous, the context clues were the most important.

Which scientist had the stronger given argument?
Scientist 2, because he/she used multiple kinds of evidence to prove their point.
Scientist 1, because he/she used context clues.
Scientist 2, because he/she used ancestry and measurements.
Neither, the two arguments are equal.
Scientist 2, because he/she used multiple kinds of evidence to prove their point.
Because multiple sources of proof strengthen an argument, Scientist 2 had the best argument.
Example Question #261 : Act Science
According to Survey 1 and Survey 2, which variable tested by the botanist had the greatest impact on average tree height?
Insect abundance
Ground soil moisture
Light level
All of these variables had an equal impact
Light level
It is clear from Table 1 and Table 2 that light level had the largest impact on average tree height. Following across many of the table rows shows that light level has a large impact, up to 7.5', on average tree height from Very Dim to Very Bright, where the other two variables only have at most a 4.3' impact.
Example Question #262 : Act Science
Based on both Survey 1 and Survey 2, what can the botanist conclude about what will factors will encourage maximum tree growth, considering that the forest is mostly average and bright light level areas?
The trees grow the same height no matter what factors are involved
Keeping up soil moisture is more significant than keeping down insect abundance
There is not a difference in height between Average and Bright light level areas
Insects, on average, are the most detrimental factor to tree growth
Keeping up soil moisture is more significant than keeping down insect abundance
The correct answer is that ground soil moisture is more significant than insect abundance. If you compare the average and bright light level columns in Table 1 and Table 2, you can see that there is much more of a difference in height by ground soil moisture than insect abundance.
Example Question #263 : Act Science
Considering that the normal human body temperature is 37 degrees Celsius and the normal body pH is 7.4, what can the researcher conclude about the effectiveness of this antibiotic in humans?
This antibiotic is at its least effective conditions
This antibiotic is most effective at a temperature of 37 degrees C, but not at a pH of 7.4
This antibiotic is at its most effective conditions
These variables are not represented in the scientist's experiments
This antibiotic is at its least effective conditions
The correct answer is that the antibiotic is at its least effective at a temperature of 37 degrees Celsius and a pH of 7.4, although there is not a great deal of difference. This could be significant for dosages of this antibiotic, however.
Example Question #261 : Biology
Which statement best describes the outcome of the experiments in this study?
Temperature changes have more of an effect on this antibiotic's effectiveness than pH changes
This antibiotic will only effectively destroy bacteria at a temperature of degrees Celsius or lower
This antibiotic is at least effective at doses of or higher
pH changes have more of an effect on this antibiotic's effectiveness than temperature changes
This antibiotic is at least effective at doses of or higher
The correct answer is that this antibiotic is at least 90% effective at all doses greater than . No matter what the value of the two variables (experimental temperature and experimental pH), the antibiotic kills greater than 90% of the bacteria in the experiment when it is at least .
