Sentences (A) to (F) describe various aspects of Google and its services: (A) But those apps are just a hint of what this Internet behemoth offers. (B) Gmail, Google Maps, and Blogger are used widely. (C) By now, most know that Google is about far more than search. (D) Under the hood of its famous search engine. (E) Here is a rundown of some useful Google gems that. (F) You may not know about, but probably should. Rearrange these sentences to form a meaningful paragraph. Which of the following sequences is correct?

Introduction / Context:
This question tests skills in paragraph formation and logical ordering of sentences. Six fragments about Google, its search engine, and various applications must be arranged into a coherent paragraph. A good paragraph moves smoothly from general statements to specific examples and finally to a purpose statement that leads into a list or explanation. We must therefore look for a natural starting sentence and then order the remaining sentences so that pronouns and linking words such as but and those apps have clear references.

Given Data / Assumptions:

• Sentence B: Gmail, Google Maps, and Blogger are used widely.
• Sentence C: By now, most know that Google is about far more than search.
• Sentence D: Under the hood of its famous search engine.
• Sentence A: But those apps are just a hint of what this Internet behemoth offers.
• Sentence E: Here is a rundown of some useful Google gems that.
• Sentence F: You may not know about, but probably should.
• We want a logical flow that introduces Google, mentions known apps, adds contrast, and then previews a list.

Concept / Approach:
The best way is to identify the most suitable opening line and then follow the references. Sentence C looks like a natural introduction because it mentions Google and contrasts it with the idea of search alone. Sentence B then provides concrete examples of widely used Google services. Sentence A begins with the word but and talks about those apps, which naturally refers back to Gmail, Maps, and Blogger mentioned in B. Sentence D seems to expand on what lies under the hood of the search engine, leading into less visible tools. Finally, sentences E and F together form a complete thought that introduces a rundown of useful Google gems you may not know about. We now compare this logical sequence with the options given.

Step-by-Step Solution:
Step 1: Choose an introductory sentence. Sentence C, By now, most know that Google is about far more than search, works well because it sets the context and topic.Step 2: After C, it is natural to mention some of the well known Google products, so sentence B, which lists Gmail, Google Maps, and Blogger, fits as the second sentence.Step 3: Sentence A begins with But those apps, so those apps clearly refer back to Gmail, Maps, and Blogger, making A the next logical sentence.Step 4: Sentence D, Under the hood of its famous search engine, naturally follows by hinting that there is more going on inside Google than what appears on the surface.Step 5: Sentences E and F together complete the thought: Here is a rundown of some useful Google gems that you may not know about, but probably should. So E must be followed by F.Step 6: Putting this together gives the order B C D A E F. This matches option C (BCDAEF).

Verification / Alternative check:
Check that pronouns and connectors have clear referents. In sentence A, those apps clearly refers to the apps just mentioned in B.Check that the phrase this Internet behemoth in A refers smoothly back to Google introduced in C.Confirm that E and F combine to form a grammatically complete sentence that introduces the rundown promised by the paragraph.

Why Other Options Are Wrong:
Option A (DECBFA) starts with D, which is a fragment and does not introduce Google or the topic clearly. It also places A at the end, which breaks the contrast pattern.Option B (EDCFBA) starts with E, but E is incomplete without F and reads abruptly without context.Option D (DCEBFA) again starts with D and later produces an awkward order where widely used apps are mentioned after the promise of a rundown, which is less smooth.

Common Pitfalls:
Many learners focus only on apparent sentence pairs like E and F and ignore the importance of reference words like those and this, leading to broken paragraphs.Another pitfall is underestimating the need for a clear introductory statement that names the main topic before examples and contrasts appear.

Final Answer:
The only sequence that forms a smooth, meaningful paragraph is BCDAEF, which is option C.
