Bộ đề ôn thi THPT 2026 giải chi tiết cực hay liên hệ Zalo O988166193 để mua ạ

If cruise lines were to ignore these growing problems, they would risk losing access to popular ports
completely. Barcelona and Venice have already taken strong action against mass tourism, creating strict
rules to protect their historical centers from too many visitors. Amsterdam shows this problem clearly:
(18)_________, locals believe they cause especially big disruptions to daily life. Local communities, tired of
constant tourist crowds, have organized protests asking for better tourism policies. Santorini and Dubrovnik
now limit daily visitor numbers, forcing cruise companies to change their schedules. Whether economic
benefits are worth environmental damage (19)_________, who once happily welcomed tourist money.
Infrastructure problems have become very obvious during busy season when several ships arrive together.
These restrictions try to protect destinations for future generations, (20)_________. Tourist taxes have
become one solution, creating money for infrastructure improvements while possibly reducing visitor
numbers. Port authorities understand the need for balance; (21)_________. Environmental concerns add
another problem to these discussions. In the future, cruise companies will need to adapt how they operate to
respect these new rules. They might consider using smaller vessels, (22)_________, and working closely
with local shops and restaurants to prove they care about sustainable tourism. The success of these efforts
depends on everyone working together—cruise lines, local governments, and community members must
find solutions that benefit all parties equally.



The Growth of Flexible Payment Plans



A 2025 study examined how Americans use short-term financing services, allowing delayed purchase
payments. These programs, splitting costs into four equal payments without extra fees, have grown
significantly since 2019. Research shows that around twenty percent of Americans with credit histories
used leading providers during 2022. Many customers were frequent participants, obtaining several
agreements monthly. Investigators found that holding multiple simultaneous contracts was common,
with sixty-five percent managing overlapping deals from different companies.



User Demographics and Debt Patterns



The study revealed concerning patterns about customer characteristics. People with poor credit ratings
receive large portions of this financing. Young adults between eighteen and twenty-four depend heavily
on these programs, which represent a bigger portion of their total debts compared to older groups.
Customers generally have higher amounts of other debts—including credit cards, personal loans, and
store accounts—than non-users. This evidence indicates these programs work mainly as extra borrowing
rather than replacing traditional options, therefore increasing financial pressure for struggling families.



Default Rates and Hidden Problems



Interestingly, non-payment rates stay low at about two percent yearly, much lower than credit card
failures among similar customers. Automatic payment systems may explain this result, though they
could hide serious financial difficulties among heavy users. A major issue involves poor reporting to
monitoring organizations. Because most companies avoid sharing contract details with regular agencies,
these obligations remain invisible in the credit system. Therefore, banks, government officials, and
borrowers cannot properly judge total debt levels.



Regulatory Uncertainty and Future Implications



Government oversight remains unclear. Although authorities previously tried classifying providers
under existing protection laws, recent statements showed reduced enforcement plans. This creates
confusion about future monitoring methods and safety measures. The research describes these programs

as popular but poorly regulated tools increasingly used by financially weak populations, highlighting the
need for better policies as this trend continues to change American borrowing habits.
https://files.consumerfinance.gov/tc
Question 23: All of the following are mentioned EXCEPT _________.
A. The specific income requirements for qualifying for these payment programs

Read the following passage about the A Game-Changer for Cancer Care and mark the letter A, B, C
or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.
An important meta-analysis published in 2025 has broken new ground in proving medical marijuana
helps cancer patients. [I] This complete review looked at over 10,600 peer-reviewed studies, making it the
largest investigation into cannabis-based cancer treatments ever done. The findings leave no room for
doubt about marijuana's medical value, with researchers finding an "overwhelming scientific consensus"

supporting its use. This major research changes how healthcare professionals think about alternative
treatments for cancer patients around the world.
The study showed that medical cannabis clearly reduces many cancer-related symptoms. Patients
suffering from chronic pain, severe nausea, vomiting, appetite loss, inflammation, and extreme tiredness
found real relief through marijuana use. [II] These improvements went beyond physical comfort, as people
reported feeling emotionally better while dealing with difficult cancer therapy. Such wide-ranging benefits
explain why more healthcare providers are now considering different approaches to helping patients manage
their symptoms.
Besides helping with symptoms, the analysis discovered promising anti-cancer properties in
cannabinoid compounds. [III] THC and CBD seem to stop tumor cells from growing, reduce their spread,
and trigger apoptosis—the process that makes cancer cells destroy themselves. While these biological
effects need more
Bộ đề ôn thi THPT 2026 giải chi tiết cực hay liên hệ Zalo O988166193 để mua ạ

clinical testing, the similar results across many studies suggest great therapeutic possibilities.
Scientists point out that current regulations have slowed down both research progress and patient access,
even though growing evidence shows cannabis is safe and well-tolerated by different groups of people.
The researchers want medical marijuana to become part of standard cancer care immediately. They
argue that old-fashioned regulations keep blocking scientific progress while preventing patients from
getting potentially helpful treatments. The meta-analysis asks policymakers, doctors, and healthcare systems
to rethink cannabis's place in modern cancer treatment. [IV] With millions of cancer patients worldwide
looking for better treatment options, the authors believe caring, evidence-based cannabis treatments could
greatly improve patients lives. This complete study challenges old beliefs and supports new approaches to
cancer care.

Question 1:A. availability

B. availably

C. avail

D. available

Giải Thích: Kiến thức về từ loại
A. availability – SAI – Từ này đóng vai trò là một danh từ trong tiếng Anh dùng để chỉ sự sẵn có hoặc tính
hữu dụng của một vật phẩm hay dịch vụ nào đó trong thực tế. Trong cấu trúc của câu văn đang xét, vị trí
trống nằm ngay sau động từ liên kết to be là is nên về mặt ngữ pháp chúng ta cần một tính từ để bổ nghĩa
trực tiếp cho chủ ngữ là loại bột sâu quy. Nếu cố tình sử dụng danh từ ở vị trí này thì câu văn sẽ trở nên lủng
củng và không thể hiện rõ ràng trạng thái có thể tìm mua được của sản phẩm trên thị trường EU. Việc lựa
chọn một danh từ không phù hợp với cấu trúc câu liên kết sẽ làm giảm đi tính chuyên nghiệp và độ chính
xác của một thông báo mang tính thương mại chính thức như bản tin này.
B. availably – SAI – Đây là một trạng từ thường được sử dụng để bổ trợ ý nghĩa cho các động từ thường
hoặc các tính từ khác nhằm làm rõ cách thức hoặc mức độ của một hành động. Tuy nhiên theo quy tắc ngữ
pháp tiếng Anh cơ bản thì trạng từ không bao giờ được phép đứng ngay sau động từ to be để đóng vai trò
làm thành phần bổ ngữ cho chủ ngữ của câu. Việc đặt một trạng từ vào vị trí này sẽ tạo ra một lỗi sai nghiêm
trọng về mặt cấu trúc và khiến người đọc cảm thấy khó hiểu về mặt ngữ nghĩa. Vì mục tiêu của câu là miêu
tả tính chất sẵn có của sản phẩm nên việc dùng trạng từ là hoàn toàn không chính xác và vi phạm các chuẩn
mực ngôn ngữ cần thiết trong văn phong viết quảng cáo.
C. avail – SAI – Từ này có thể được sử dụng như một động từ mang nghĩa là giúp ích hoặc tận dụng một
điều gì đó hoặc đóng vai trò danh từ trong các cụm từ cố định mang nghĩa vô ích. Xét về mặt cấu trúc ngữ
pháp thì việc đặt một động từ ở dạng nguyên mẫu đứng ngay sau động từ to be mà không có các cấu trúc hỗ

trợ khác là hoàn toàn sai lệch. Hơn nữa về mặt ngữ nghĩa thì từ này không phản ánh đúng thông điệp mà
nhãn hàng muốn truyền tải là sản phẩm đã chính thức có mặt để khách hàng lựa chọn mua sắm. Lựa chọn
này sẽ khiến câu văn bị đứt gãy về mặt logic và làm sai lệch đi hoàn toàn ý định ban đầu của người viết
trong việc giới thiệu sự hiện diện của sản phẩm mới.
D. available – ĐÚNG – Đây là một tính từ mang ý nghĩa là sẵn có hoặc có sẵn để dùng và nó hoàn toàn
tương thích với vị trí đứng sau động từ to be để miêu tả trạng thái của chủ ngữ. Trong các văn bản quảng cáo
hoặc thông tin thị trường thì tính từ này là lựa chọn tối ưu nhất để thông báo tới khách hàng rằng một mặt
hàng nào đó hiện đã được bày bán chính thức. Nó giúp câu văn trở nên mạch lạc và giúp người tiêu dùng
hiểu ngay lập tức rằng họ có thể tìm thấy sản phẩm này trên thị trường Liên minh Châu Âu. Việc sử dụng
đúng tính từ ở đây không chỉ đảm bảo đúng quy tắc ngữ pháp mà còn tăng cường hiệu quả truyền thông và
tính chuyên nghiệp cho toàn bộ đoạn văn bản quảng bá sản phẩm.
Tạm dịch: Our environmentally friendly mealworm powder is now available in the EU market! (“Bột sâu
quy thân thiện với môi trường của chúng tôi hiện đã có sẵn trên thị trường EU!”)

Question 2:A. that

B. where

C. which

D. who

Giải Thích: Kiến thức về MĐQH
A. that – SAI – Đại từ quan hệ này thường được dùng rất phổ biến để thay thế cho cả danh từ chỉ người và
vật trong các mệnh đề quan hệ xác định mang tính thiết yếu cho câu. Tuy nhiên một quy tắc bất di bất dịch
trong ngữ pháp tiếng Anh là không được sử dụng đại từ này trong các mệnh đề quan hệ không xác định tức
là mệnh đề nằm giữa hai dấu phẩy. Vì trong câu hỏi có sự xuất hiện của dấu phẩy ngay trước chỗ trống để
ngăn cách thông tin bổ sung về việc phê duyệt của Ủy ban Châu Âu nên việc dùng từ này là hoàn toàn sai.
Lỗi sai này sẽ làm cho văn bản trở nên kém chuẩn mực và không phù hợp với các yêu cầu khắt khe về mặt
ngôn ngữ đối với các tài liệu chính thức của các tổ chức quốc tế.
B. where – SAI – Đây là một trạng từ quan hệ được dùng để thay thế cho các danh từ chỉ nơi chốn hoặc địa
điểm trong một mệnh đề quan hệ nhằm làm rõ không gian xảy ra hành động. Trong ngữ cảnh này thì danh từ
đứng trước chỗ trống là innovative product tức là một sản phẩm mang tính sáng tạo và đây là một danh từ
chỉ sự vật chứ không phải địa danh. Do đó việc sử dụng một từ chỉ nơi chốn để bổ nghĩa cho một sản phẩm
vật chất là hoàn toàn phi lý và sai lệch về mặt bản chất ngữ nghĩa của câu. Người đọc sẽ cảm thấy sự thiếu
logic trong việc trình bày thông tin nếu chúng ta chọn phương án này vì nó không thể kết nối đúng mối quan
hệ giữa sản phẩm và hành động phê duyệt của các cơ quan quản lý.
C. which – ĐÚNG – Đây là đại từ quan hệ được sử dụng để thay thế cho danh từ chỉ sự vật hoặc động vật
và nó hoàn toàn được phép xuất hiện trong các mệnh đề quan hệ không xác định có dấu phẩy. Vì đối tượng
được nhắc đến ở đây là một sản phẩm bột sâu quy và thông tin phía sau chỉ là phần bổ sung thêm để tăng độ
tin cậy nên việc dùng từ này là lựa chọn duy nhất đúng. Nó giúp kết nối mệnh đề phụ về việc được phê
duyệt bởi Ủy ban Châu Âu với mệnh đề chính một cách chính xác về mặt ngữ pháp. Việc sử dụng đại từ này
đảm bảo cho câu văn vừa cung cấp đầy đủ thông tin vừa tuân thủ đúng các quy tắc về dấu câu và cấu trúc
mệnh đề trong văn phong tiếng Anh chuẩn mực nhất.

D. who – SAI – Đại từ quan hệ này chỉ được dùng để thay thế cho các danh từ chỉ ngườ
