"Ce que" and "qui" are used in French to introduce relative clauses, while "nur que" and "qui" are used in German. In French, "ce que" is used to introduce a relative clause that functions as the direct object of the main clause, while "qui" is used to introduce a relative clause that functions as the subject of the main clause. In German, "nur que" is used to introduce a relative clause that functions as the direct object of the main clause, while "qui" is used to introduce a relative clause that functions as the subject of the main clause. **

We use "ce qui" when the subject of the verb is unknown or unspecified. "Ce que" is used when the object of the verb is unknown or unspecified. "Qui" is used as the subject of the verb, while "que" is used as the direct object of the verb. "Dont" is used to indicate possession or relationship, and "lequel" is used to refer to a specific noun that has been previously mentioned. **

"Que qui est ce que qui" is not a standard phrase in French. It seems to be a combination of different question words and does not form a coherent question. "Que" means "what," "qui" means "who," and "est-ce que" is a phrase used to form yes/no questions. However, the combination of these words in this order does not make sense in French. It is possible that there was a mistake in the original question or that it was a typo. **

Qui quae quod is a Latin demonstrative pronoun that means "who," "which," or "what." It is used to refer to people, things, or ideas in a relative or interrogative context. In English, it can be translated as "who," "which," or "what," depending on the context in which it is used. **

One can abbreviate 'que qui' by using the abbreviation 'qq' in written communication. This abbreviation is commonly used in French to represent both 'que' and 'qui' in a more concise form. It is important to note that using abbreviations like 'qq' may be informal and should be used appropriately depending on the context. **

"Ce que" is used when the relative pronoun refers to an abstract idea or an entire clause, while "que" is used when it refers to a specific thing or person. For example, "Je sais ce que tu veux" (I know what you want) and "Je sais que tu veux partir" (I know that you want to leave). On the other hand, "ce qui" is used when the relative pronoun refers to the subject of the following clause, while "qui" is used when it refers to the subject of the main clause. For example, "Ce qui m'étonne, c'est qu'il soit parti" (What surprises me is that he left) and "La personne qui m'a aidé" (The person who helped me). **

Organic products are made from ingredients that are grown without the use of synthetic pesticides, herbicides, or fertilizers, and are often certified by a regulatory body. Eco-friendly products, on the other hand, are designed to have minimal impact on the environment throughout their entire lifecycle, from production to disposal. While organic products focus on the natural ingredients used, eco-friendly products consider the overall environmental impact of the product. In essence, organic products focus on the ingredients, while eco-friendly products focus on the entire product lifecycle. **

Organic farming practices can be more sustainable than conventional methods in terms of reducing chemical inputs, promoting biodiversity, and improving soil health. However, there are challenges to the scalability and efficiency of organic farming, which can impact its overall sustainability. For example, organic farming typically requires more land and labor to produce the same amount of food as conventional methods, which can limit its ability to meet global food demand. Additionally, the transportation and distribution of organic products can have a higher environmental impact due to their shorter shelf life and the need for refrigeration. Overall, while organic farming has many sustainable benefits, there are also limitations to its long-term sustainability on a large scale. **
