1.The information in the graph_______________the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005.

The %age increase/decrease in the number of international immigrants in France during the period from 1980 to 2005: 11, 10.9, 10.2,10.3,10.3,11,but
we don't know the population of France at the start of 1998, so we cannot actually infer that the population increased or decreased, could be could not be.
So we have nothing to compare the increase/decrease in the above %ages.

Thus the information in the graph neither directly affirms nor directly contradicts.
Answer C.


2. During the interval________________the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

It can be easily inferred from the graph that for the period:
1980–1995 - US seems to higher growth as compared to other countries.
1980–2005 - US does have less growth for the given period, but its too long a period, US has higher growth in the middle years, in comparison to other countries.
1995–2005 - In this particular period, we see that Ireland has a better and visible growth than US.

Answer C.

Question 1 : C
1. The information in the graph_______________the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005.

A. directly affirms
B. directly contradicts
C. neither directly affirms nor directly contradicts


The graph represents the France % of total population, and that stays almost the same. But, we have to note here that the total population itself can go in either direction. Hence, we can't say anything about the number of international immigrants.

Question 2: C
2. During the interval________________the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

A. 1980–1995
B. 1980–2005
C. 1995–2005


In 1980-1985, US' rate of growth of population is from 6 to 7.2%. All other countries grow at a lesser % in these 5 yrs.
In 1985-1990, US' rate of growth of population is from 7.2 to 9%. All other countries grow at a lesser % in these 5 yrs. Ireland grows from 8-9% of total population.

In the other years, Ireland surpasses this %. Hence C.

In question 2,
For the interval 1980-2005

% change for US = 13-6 = 7%

% change for Ireland = 14-6 = 8%

In this interval too, the change is lower for US

So, B is also a valid answer.

Can someone explain Q2? Why can't A be the answer? US is clearly below at least one of France and Sweden during those 15 years.

Official Explanation

The scale on the graph's vertical axis represents the percentage of a country's population who are international immigrants. The line representing France is relatively flat, showing that the percentage of the people in France who were international immigrants did not change much from 1980 to 2005. But the graph does not indicate whether the number of people constituting France's total population changed significantly during that period. If France's population did change significantly, while the percentage of that population consisting of international immigrants remained about the same, then the graph would indicate that the number of international immigrants also changed significantly during that period. On the other hand, if France's population did not change significantly, then the graph would indicate that the number of international immigrants did not either. Thus, the graph neither directly affirms nor directly contradicts the statement that the number of international immigrants in France did not change significantly from 1980 to 2005.

The correct answer is neither directly affirms nor directly contradicts.

In the graph, the slope of the line representing any country represents that country's rate of growth in international immigrants as a percent of total population, with a steeper upward slope from left to right indicating faster growth. In both the section of the graph representing the period from 1980 to 1985 and the section representing the period from 1980 to 1995, the line representing the United States slopes upward from left to right more steeply than each of the other lines, indicating that the rate of growth in international immigrants as a percent of total population was greater in the United States than in each of the other nations during those periods. But in the section of the graph representing the period from 1995 to 2005, the line representing Ireland slopes upward from left to right more steeply than the line representing the United States does, indicating that the rate of growth in international immigrants as a percent of total population was greater in Ireland than in the United States during the interval from 1995 to 2005.

The correct answer is 1995–2005.

Hi,
In Q2 why cannot the period from 1980 to 2005 be the answer?
In 1980 to 2005 US grew by 7%, and Ireland by 8%.
So US is below at least one other country?

Please advise where I am going wrong.

The question is talking about the "rate of growth" and not the particular point of growth. So from the period of 1995-2000 Irelands rate of growth is more than the United states rate of growth. During the period 1980-2000, no other country has the greater rate of growth than the United State.

Hey CEdward,

I have the same question, I also chose the A (1980-1985).
The only reason I can think is that the question asks for the rate of growth so in this way implies the change of international immigrants as a percent of total population.

Could somebody help us? Bunuel KarishmaB GMATNinja GMATinsight GMATCoachBen

­Gmatguy007 Yes, exactly! The key is understanding that "RATE of growth" means the SLOPE of the line (change in Y / change in X). A rate of growth normally has the time frame in the denominator.

From 1995 to 2005, we see that the slope for the green line for the United States is lower (less steep) than the blue dashed line for Ireland:

­Great, thank you GMATCoachBen !
Also, we can focus solely on the lines of USA and Ireland since both France and Sweden have relative constant rate of growth as we can see from the graph, right?

Thank you in advance 😀

@Gmatguy007 ­We always focus on exactly what it's asking for!

The question says: 

2. During the interval _____ the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

So, we are looking for a part of a line that is STEEPER than the United States' line, so our eye should immediately focus on the steepest part of one of the lines -- we see that it's Ireland from 1995 to 2005. There can only be one answer, so we can stop there.

If we look at France and Sweden's lines, we can quickly see that they are not steeper than the United States' line.

Official Explanation

In the graph, the slope of the line representing any country represents that country's rate of growth in international immigrants as a percent of total population, with a steeper upward slope from left to right indicating faster growth. In both the section of the graph representing the period from 1980 to 1985 and the section representing the period from 1980 to 1995, the line representing the United States slopes upward from left to right more steeply than each of the other lines, indicating that the rate of growth in international immigrants as a percent of total population was greater in the United States than in each of the other nations during those periods. But in the section of the graph representing the period from 1995 to 2005, the line representing Ireland slopes upward from left to right more steeply than the line representing the United States does, indicating that the rate of growth in international immigrants as a percent of total population was greater in Ireland than in the United States during the interval from 1995 to 2005.

The correct answer is 1995–2005.
­Hi Sajjad1994

For question 2, I noticed a difference in the answer choices in the question's dropdown and answer choices as per official answer. 

As per Question
1980-1995
1980-2005
1995-2005

As per Official Explanation posted:
1980-1985
1980-1995
1995-2005

From choices in Official explanation, only 1995-2005 satisfies the criteria 

However, from choices in Question, both 1980-2005 and 1995-2005 seem to satisfy the criteria.­

With the question below
"­The information in the graph ______ the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005."

Hey GMATCoachBen given a statement such as the one above, do we care about the change in number of international immigrants by comparing data in the 2 specific years 1980 vs 2005 OR do we look at the changes over each year between and including 1980 and 2005? I appreciate that this does not make a difference in this question, but it was something that crossed my mind. Of course, let me know if I am overanalysing things.­

Thank you and appreciate all your responses here on GMATClub!­
