Answer Explanation:
Answer: 1993 | 0.6
By following the gridline at 60°C, the visible line indicating the solubility of NaNO3 is highest on the graph. However, the line for Kl extends above the scale shown on the graph. So, given the assumption that the curves continue in the same general shape beyond the plotted area, the information given indicates that Kl is the most soluble at 60°C. The correct answer is KI.
Two-Part Analysis
Two-Part Analysis questions assess your ability to solve complex problems with multiple components. You will be presented with a question and two possible answer choices, and your task is to select one answer for each part. This question type measures your analytical and decision-making skills.
Tip: Break down the problem into smaller parts and tackle each part systematically. Consider all the given information before making your choices.
Archeologists excavating at a certain site have found the following five artifacts: a bowl, a cup, a jug, a statue, and an urn. At this site, the greater the depth at which an artifact was found, the older that artifact is. The bowl was determined to be x years old and was found at a depth of d meters. Both the cup and the jug were found at a depth of less than d meters. The statue was determined to be 1.5x years old, and the urn was found at a greater depth than the statue was.

Answer Explanation:
Answer:
Must be true The median of the artifacts' ages is x years Must be false The urn is less than 1.5x years old- must be false. The greater the depth at which an artifact was found, the older that artifact is.
The bowl was determined to be x years old and was found at a depth of d meters.
Both the cup and the jug were found at a depth of less than d meters.
The statue was determined to be 1.5x years old, and the urn was found at a greater depth than the statue was.
The order of age from oldest to youngest is: urn, statue, bowl, {cup, jug}. The order of depth from deepest to shallowest is: urn, statue, bowl, {cup, jug}.
"Must be True" choice:
"The median of the artifacts' ages is x years." To evaluate this statement, we need to arrange the artifacts in the order of their age. The median is the middle value when all values are sorted in ascending or descending order. Here, the bowl is the middle artifact in terms of age, and the bowl is x years old. Therefore, the median age is x years.
"Must be False" choice:
"The urn is less than 1.5x years old." Given that the urn was found at a greater depth than the statue, and that a greater depth corresponds to an older age, we can deduce that the urn is older than the statue. We know the statue is 1.5x years old, so the urn must be older than 1.5x years. Therefore, the statement "the urn is less than 1.5x years old" must be false.

Answer Explanation:
Answer:
Loan proceeds: 0.8n
Repayment amount: 1.00n
In this question, the business borrows an amount up to 85% of their collateral assets value, but that loan amount is given to them after deducting the 20% interest upfront. This means, for a loan of amount 'n', the actual loan proceeds (amount received by the business) would be 'n - 0.2n' which equals '0.8n'.
And, when it comes to repayment, the business needs to pay back the original loan amount, which is 'n', regardless of the deducted interest.
Table Analysis
Table Analysis questions require you to interpret and analyze data presented in a table format. You may need to sort, filter, or perform calculations to answer the associated questions. This question type assesses your ability to extract valuable insights from organized data.
Tip: Take note of any patterns, trends, or outliers in the data. Focus on the columns and rows that are directly related to the questions.
Parliamentarians in Nation X are debating how national government funds allocated for education should be distributed to the country's 23 provinces. According to Parliamentarian 1, when a province has a greater number of children under 18 years of age than another province has, the province with the greater number of children should receive more funding. Parliamentarian 2 states that when one province contributes more in taxes to the national government than another province contributes, the province that contributes more should receive more funding. Current data for the 23 provinces are provided in the table.

spellcheck Check Answer & Answer Explanation
Answer Explanation:
Statement 1: The current distribution of educational funding satisfies the condition recommended by Parliamentarian 1.
Parliamentarian 1's condition is that provinces with a greater number of children under 18 should receive more funding. If we look at the data, we can see that provinces with more children under 18 generally receive more funding. For instance, Province N has the highest number of children under 18 (1283 thousand) and also receives the highest funding (4851 thousand dollars). Therefore, the answer is Yes.
Statement 2: The current distribution of educational funding satisfies the condition recommended by Parliamentarian 2.
Parliamentarian 2's condition is that provinces that contribute more in taxes should receive more funding. However, if we look at the data, this condition is not always met. For example, Province A contributes more in taxes (22648 million dollars) than Province E (30601 million dollars), but Province E receives more funding (4030 thousand dollars) than Province A (2688 thousand dollars). Therefore, the answer is No.
Statement 3: The current distribution of educational funding satisfies neither of the conditions proposed by the parliamentarians.
Since the first statement is accurate (the distribution of funding does satisfy Parliamentarian 1's condition), this statement is not accurate. Therefore, the answer is No.
Multi-Source Reasoning
In Multi-Source Reasoning questions, you will be presented with information from multiple tabs or sources, such as tables, graphs, or text. Your task is to use this data to answer multiple related questions. This question type evaluates your ability to synthesize information from different sources.
Tip: Read the questions before diving into the sources. Look for keywords that will help you focus on the relevant information in each source.
Company X Values Statement In accordance with our mission statement, Company X has the following fundamental values:
- People Helping People: Helping clients and employees to reach their personal goals.
- Dedication to Exceptional Service: Exceeding quality of service expectations by recognizing opportunities to provide financial solutions that fulfill our clients' needs.
- Commitment to Education: Actively promoting the education of our clients, our employees, and members of the community in which we do business, so they may attain the highest level of development both financially and personally.
Integrity: Being respectful and reliable in all of our relationships.

A determination that the action does not maximize return on investment for shareholders |
-
spellcheck Check Answer & Answer Explanation
Answer Explanation:
(1) A determination that the action is legal - May perhaps not have occurred
The Values statement does not explicitly mention legality, so it's possible that the legality of the action was not considered. The ethics procedure is concerned with the company's values and the potential consequences of the action, rather than its legality.
(2) A determination that the action maximizes return on investment for shareholders - May have occurred
While the Values statement does not explicitly mention maximizing return on investment for shareholders, it does mention "providing financial solutions that fulfill our clients' needs." This could potentially include maximizing return on investment for shareholders, so it's possible that this determination was made.
(3) A determination that the action does not maximize return on investment for shareholders-May perhaps not have occurred
Similar to the previous point, while the Values statement does not explicitly mention maximizing return on investment for shareholders, it does mention "providing financial solutions that fulfill our clients' needs." This could potentially include maximizing return on investment for shareholders, so it's possible that this determination was not made
Data Sufficiency
In a DS question, you are provided with a question and two separate statements containing information related to the question. The task is not to solve the problem but to determine whether the given statements individually or in combination provide sufficient data to answer the question. You must evaluate each statement independently and then analyze their combined effectiveness in arriving at a definitive answer. Mastering the DS type requires the ability to think critically, identify relevant data, and apply quantitative reasoning skills efficiently.

spellcheck Check Answer & Answer Explanation
Answer Explanation:
Answer:(E)
Let the initial investment in venture A be denoted as 'a', and the initial investment in venture B be 'b'.
The question is asking for the value of 'b'.
Statement (1):
This statement tells you that the initial investment in venture B is five times the initial investment in venture A.
In mathematical terms, this gives you b = 5a.
However, without knowing the value of 'a', you cannot determine the value of 'b'. Thus, statement (1) alone is not sufficient.
Statement (2):
This statement tells you that 'a' dollars earning interest at a rate of 5k% equals $50, and 'b' dollars earning interest at a rate of 3k% equals $150.
This gives you two equations: 5k/100 * a = $50 and
3k/100 * b = $150.
Manipulating these equations, we get:
a = $50 / (5k/100) and
b = $150 / (3k/100)
Dividing, these we get,
a/b = 1/5
However, we can't figure out the individual values of 'a' and 'b' as the value of 'k' is not given. So, statement (2) alone is also not sufficient.
Taking BOTH statements TOGETHER, we still can't determine the value of 'b' because we do not know the value of 'k'. Both statements together simply confirm that b = 5a, but without the value of 'k', we cannot determine the individual values of 'a' and 'b'. Therefore, BOTH statements TOGETHER are NOT sufficient.
The correct answer is (E).
