"Passive transport occurs when a substance passes through the cell membrane without needing any energy to pass through. This happens when a substance moves from an area where it is more concentrated to an area where it is less concentrated. Concentration is the number of particles of a substance in a given volume. Let's say you dissolve a teaspoon of salt in a cup of water. Then you dissolve two teaspoons of salt in another cup of water. The second solution will have a higher concentration of salt."
"A man put two cups, cup A and cup B, filled with equal amounts of water on to a table and walked away to go check his mail. His son came along and saw the two cups and decided to put some sugar in them to make a tasty drink. The child poured two spoonfuls of sugar into cup A and three spoonfuls of sugar into cup B."
"Which cup has a higher concentration of sugar?"

"As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell’s requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli ."
"There are two cells inside a Petri dish in a laboratory, cell X and cell Z. These cells are from the same organism, but are not the same age. Cell X was created two weeks ago, and cell Z was created one month ago. Therefore, cell Z has had two extra weeks of growth compared to cell X."

"Gary, a high school student, is supposed to be studying two different cells under a microscope during his biology class. Gary doesn't like biology class at all though and can't find the motivation to look at the cells in detail. In his homework where students are supposed to write what they observed, Gary simply wrote down the first thing he saw under the microscope which was that Cell A is larger than cell B. It won't get him a great grade, but Gary is hoping it will at least get him a pass on the assignment."

"Look at the police car in Figure below . The sound waves from its siren travel outward in all directions. Because the car is racing forward (toward the right), the sound waves get bunched up in front of the car and spread out behind it. As the car approaches the person on the right (position B), the sound waves get closer and closer together. In other words, they have a higher frequency. This makes the siren sound higher in pitch. After the car speeds by the person on the left (position A), the sound waves get more and more spread out, so they have a lower frequency. This makes the siren sound lower in pitch. A change in the frequency of sound waves, relative to a stationary listener, when the source of the sound waves is moving is called the Doppler effect . You’ve probably experienced the Doppler effect yourself. The next time a vehicle with a siren races by, listen for the change in pitch. For an online animation of the Doppler effect, go to the URL below."

"Most chemical reactions within organisms would be impossible under the conditions in cells. For example, the body temperature of most organisms is too low for reactions to occur quickly enough to carry out life processes. Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst. A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes . Essentially, enzymes are biological catalysts."

"When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ).

"The particles of soup have greater average kinetic energy than the particles of water in the tub, explaining why the soup has a higher temperature. However, the mass of the water in the tub is much greater than the mass of the soup in the pot. This means that there are many more particles of water than soup. All those moving particles give the water in the tub greater total kinetic energy, even though their average kinetic energy is less. Therefore, the water in the tub has greater thermal energy than the soup.

"Active transport occurs when a substance passes through the cell membrane with the help of extra energy. This happens when a substance moves from an area where it is less concentrated to an area where it is more concentrated. This is the opposite of diffusion. The substance moves up, instead of down, the concentration gradient. Like rolling a ball uphill, this requires an input of energy. The energy comes from the molecule named ATP (adenosine triphosphate). The energy allows special transport proteins called pumps to move substances to areas of higher concentration. An example is the sodium-potassium pump."

"An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing.

"The epidermis also contains melanocytes, which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D. Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency."

# Dataset Card for ROPES

### Dataset Summary

ROPES (Reasoning Over Paragraph Effects in Situations) is a QA dataset which tests a system's ability to apply knowledge from a passage of text to a new situation. A system is presented a background passage containing a causal or qualitative relation(s) (e.g., "animal pollinators increase efficiency of fertilization in flowers"), a novel situation that uses this background, and questions that require reasoning about effects of the relationships in the background passage in the context of the situation.

### Supported Tasks and Leaderboards

The reading comprehension task is framed as an extractive question answering problem.

Models are evaluated by computing word-level F1 and exact match (EM) metrics, following common practice for recent reading comprehension datasets (e.g., SQuAD).

### Languages

The text in the dataset is in English. The associated BCP-47 code is en.

## Dataset Structure

### Data Instances

Data closely follow the SQuAD v1.1 format. An example looks like this:

{
"id": "2058517998",
"background": "Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation.",
"situation": "Jason recently learned that he has cancer. After hearing this news, he convinced his wife, Charlotte, to get checked out. After running several tests, the doctors determined Charlotte has no cancer, but she does have high blood pressure. Relieved at this news, Jason was now focused on battling his cancer and fighting as hard as he could to survive.",
"question": "Whose cells are dividing more rapidly?",
"answers": {
"text": ["Jason"]
},
}


### Data Fields

• id: identification
• background: background passage
• situation: the grounding situation
• question: the question to answer
• answers: the answer text which is a span from either the situation or the question. The text list always contain a single element.

Note that the answers for the test set are hidden (and thus represented as an empty list). Predictions for the test set should be submitted to the leaderboard.

### Data Splits

The dataset contains 14k QA pairs over 1.7K paragraphs, split between train (10k QAs), development (1.6k QAs) and a hidden test partition (1.7k QAs).

## Dataset Creation

### Curation Rationale

From the original paper:

ROPES challenges reading comprehension models to handle more difficult phenomena: understanding the implications of a passage of text. ROPES is also particularly related to datasets focusing on "multi-hop reasoning", as by construction answering questions in ROPES requires connecting information from multiple parts of a given passage.

We constructed ROPES by first collecting background passages from science textbooks and Wikipedia articles that describe causal relationships. We showed the collected paragraphs to crowd workers and asked them to write situations that involve the relationships found in the background passage, and questions that connect the situation and the background using the causal relationships. The answers are spans from either the situation or the question. The dataset consists of 14,322 questions from various domains, mostly in science and economics.

### Source Data

From the original paper:

We automatically scraped passages from science textbooks and Wikipedia that contained causal connectives eg. ”causes,” ”leads to,” and keywords that signal qualitative relations, e.g. ”increases,” ”decreases.”. We then manually filtered out the passages that do not have at least one relation. The passages can be categorized into physical science (49%), life science (45%), economics (5%) and other (1%). In total, we collected over 1,000 background passages.

#### Initial Data Collection and Normalization

From the original paper:

We used Amazon Mechanical Turk (AMT) to generate the situations, questions, and answers. The AMT workers were given background passages and asked to write situations that involved the relation(s) in the background passage. The AMT workers then authored questions about the situation that required both the background and the situation to answer. In each human intelligence task (HIT), AMT workers are given 5 background passages to select from and are asked to create a total of 10 questions. To mitigate the potential for easy lexical shortcuts in the dataset, the workers were encouraged via instructions to write questions in minimal pairs, where a very small change in the question results in a different answer.

Most questions are designed to have two sensible answer choices (eg. “more” vs. “less”).

To reduce annotator bias, training and evaluation sets are writter by different annotators.
