Answer:

The last point i.e .starting from "It breaks......multiple computer " is the correct answer to the given question.

Explanation:

Hadoop distributes large data processing across a cluster of commodity servers and works on multiple machines concurrently. To process any data, the client shall submit the data and the program to Hadoop. HDFS keeps the information while MongoDB processes the data and Yarn separates the tasks.

Hadoop is an open-source software platform for data storage and running applications on heterogeneous computing clusters. It provides vast storage for any kind of data, enormous computing power, and the ability to manage virtually infinite simultaneous activities or employment.  

All the other lines are not related to Hadoop that' why they are incorrect options .

lozanna [386]

The first sentence that seems out of the logical order is the very first sentence, i.e, Also, she is moving the heavy oak bookcase to the bedroom.

A.  1

<u>Explanation:</u>

The fact that the sentence uses words like "she" and "also" leads to this conclusion. The logical order should move in a forward direction with the sentences forming a logical sequence.

The first sentence's structure is adding details to the actions which are already in progress and hence it should not be the first sentence. It should appear after the process of moving furniture has been started and further details are being added to it.
