We need to translate the Russian fragment into natural English, preserving paragraph breaks, not translating article link, url, or any proper nouns. The fragment includes some weird characters like "ƃ" which likely is a placeholder for some currency symbol? Should keep as is. Also "Onlíner" is a proper noun, keep unchanged. Also "Белавиа" is a proper noun (Belavia airline) keep unchanged. "RGK NV-64", "Garmin GPSMAP 65" keep unchanged. Also "Основные источники" is a phrase but it's part of UI; we should translate? The instruction: "Do not translate the article link, url, or any proper nouns you cannot render." "Основные источники" is not a proper noun, it's a phrase meaning "Main sources". Should translate. However they might want to keep as is? The phrase appears in "Добавить в основныеисточники Google" which is likely a button: "Add to main sources Google". Probably translate to "Add to main sources Google". But "Основные источники" is a UI term; but we can translate. The instruction says not to translate proper nouns you cannot render. This is not a proper noun. So translate.

We need to preserve paragraph breaks. Let's identify paragraphs in the original:

Paragraph 1: "Автор: Варвара Морозова. Фото: архив Onlíner"

Paragraph 2: blank line? Actually after that line there is a blank line then "Добавить в основныеисточники Google"

Paragraph 3: blank line then "КАК ВЫИГРАТЬ MACBOOK?До 27.09 заказывайте в приложении Каталог Onlíner на сумму от 99 ƃ и получите шанс выиграть MacBook или ещё 18 призов!"

Paragraph 4: blank line then "Купили билет на самолет, а планы поменялись? Теперь, чтобы вернуть билет, не обязательно ехать в офис «Белавиа». Компания запустила соответствующую онлайн-услугу."

Paragraph 5: blank line then "Авиаперевозчик подчеркнул: оформить добровольный онлайн-возврат можно только для бронирований, в которых билет и дополнительные услуги оформлены на сайте. Если хотя бы одна услуга оформлена другим способом, вернуть билет онлайн не получится."

Paragraph 6: blank line then "Сумму возврата рассчитывают с учетом условий тарифа, по которому куплен билет."

Paragraph 7: blank line then "Туристический навигатор RGK NV-64"

Paragraph 8: blank line then "экран: 2.8''"

Paragraph 9: blank line then "1562 ƃ"

Paragraph 10: blank line then "от 45,56 ƃ/мес"

Paragraph 11: blank line then "9 предложений"

Paragraph 12: blank line then "Туристический навигатор Garmin GPSMAP 65"

Paragraph 13: blank line then "экран: TFT 2.6''"

Paragraph 14: blank line then "1672 ƃ"

Paragraph 15: blank line then "3 предложения"

Paragraph 16: blank line then "Сравнить эти товары →"

Paragraph 17: blank line then "Смотреть Туристические навигаторы в Каталоге"

Paragraph 18: blank line then "Нравится читать Onlíner? Добавьте наши новости в «Основные источники» Google"

Paragraph 19: blank line then "Есть о чем рассказать? Пишите в наш телеграм-бот. Это анонимно и быстро"

We need to translate each paragraph into English, preserving line breaks.

We must not translate proper nouns: Onlíner, Белавиа, RGK NV-64, Garmin GPSMAP 65, Каталог (maybe it's a proper noun? It's "Catalog" but could be translated; but it's part of the app name "Каталог Onlíner". Might be considered proper noun? Safer to keep as is? The instruction: "Do not translate the article link, url, or any proper nouns you cannot render." "Каталог" is not a proper noun, it's a common noun meaning catalog. Could translate to "Catalog". However it's part of the phrase "приложении Каталог Onlíner". Might be "Onlíner Catalog app". I'd translate "Каталог" to "Catalog". But "Onlíner" stays.

Also "Основные источники" translate to "Main sources". Keep quotes? The original uses «Основные источники». We'll translate to "Main sources". Keep the quotes? We can use English quotes.

We must not translate the link or URL; none present.

We must keep the weird currency symbol "ƃ". Keep as is.

We must keep the numbers and formatting.

Now translate each paragraph.

Paragraph 1: "Автор: Варвара Морозова. Фото: архив Onlíner" => "Author: Varvara Morozova. Photo: Onlíner archive"

Paragraph 2: "Добавить в основныеисточники Google" => "Add to main sources Google"

Paragraph 3: "КАК ВЫИГРАТЬ MACBOOK?До 27.09 заказывайте в приложении Каталог Onlíner на сумму от 99 ƃ и получите шанс выиграть MacBook или ещё 18 призов!" Note there is no space after question mark before "До". We'll keep as is but translate: "HOW TO WIN A MACBOOK? Until September 27, order in the Onlíner Catalog app for an amount of at least 99 ƃ and get a chance to win a MacBook or another 18 prizes!" We need to preserve the exclamation and question marks. We'll translate: "HOW TO WIN A MACBOOK? Until September 27, order in the Onlíner Catalog app for an amount of at least 99 ƃ and get a chance to win a MacBook or another 18 prizes!"

Paragraph 4: "Купили билет на самолет, а планы поменялись? Теперь, чтобы вернуть билет, не обязательно ехать в офис «Белавиа». Компания запустила соответствующую онлайн-услугу." => "You bought a plane ticket, but your plans changed? Now, to refund the ticket, you don't have to go to the Belavia office. The company has launched the corresponding online service."

Paragraph 5: "Авиаперевозчик подчеркнул: оформить добровольный онлайн-возврат можно только для бронирований, в которых билет и дополнительные услуги оформлены на сайте. Если хотя бы одна услуга оформлена другим способом, вернуть билет онлайн не получится." => "The carrier emphasized that a voluntary online refund can be made only for bookings where the ticket and additional services were issued on the website. If at least one service was issued another way, you cannot refund the ticket online."

Paragraph 6: "Сумму возврата рассчитывают с учетом условий тарифа, по
