Abstract
GRAPES-3 is an air shower array in the Nilgiri mountains in Southern India, consist- ing of a 560 m2 muon telescope (G3MT) made up of proportional counters as well as a 25000 m2 array of 400 plastic scintillator detectors. In operation since 2000, the muon telescope has proven itself to be a sensitive probe of cosmic, solar, heliospheric and at- mospheric phenomena. Recently the observatory has validated its pointing by character- izing the shadow of the moon in data gathered over multiple years. Small angular scale anisotropies have been measured in the arrival directions of cosmic rays, confirming the existence of features reported previously by HAWC and Argo-YBJ. The multiplicity distri- bution of muons measured by G3MT allows the relative composition of proton primaries to be extracted from the all-particle air shower data. The extracted proton spectrum indicates a spectral hardening at ∼ 166 TeV, disfavoring a single power law description of the proton spectrum up to the knee. These emerging capabilities of GRAPES-3 as an astroparticle physics observatory are expected to be further enhanced by the completion of a new muon telescope, presently under construction. This will double the effective area over which the muon component of air showers can be measured.

Report
This article presents the results of the Grapes-3 experiment, which confirm the success of the cosmic ray experiment. The work is of academic standard and deserves publication. However, some actions are required before publication. These recommendations aim to improve the manuscript according to the rules and quality of the journal.
Requested changes
1) The abstract should fit into 8 lines. It should be written in a clear and comprehensible style, emphasizing the context, the problem(s) studied, the methods used, the results obtained, the conclusions reached,and the outlook.
2) The English must be improved. The reviewer strongly recommends having a native English speaker read through the paper to improve the English. Use the active voice in every sentence that focuses on the doer of the action. Many passive sentences cloud the meaning of the sentences. The reviewer recommends using the active voice whenever possible. Sentences in the passive voice often use more words, can be vague, cloud the meaning and lead to a jumble of prepositions. The active voice emphasizes the subject, i.e. the person performing the action. The passive voice, on the other hand, emphasizes the action or the recipient of the action. For example:
a) At the end of Abstract, in the next sentence, it is unclear who or what THIS refers to, and the passive voice does not contribute to clarity
“This will double the effective area over which the muon component of air showers can be measured”
3) In all figures, you must cite the figures as the source and give credit. For example: Credit AUTHOR (REFERENCE). Due to editorial rules and copyrights, it is necessary to cite more than just the source (see References) or similar. It is best to use typical rules such as "modified by xxx(yyyy)" or "based on xxx (yyyy)" , "Adapted from [reference to the original article], "with permission from [copyright holder]" or similar, depending on the context. Also use Creative Commons Attribution 4.0 International (CC-BY-4.0) if appropriate. ( https://creativecommons.org/licenses/by/4.0/ )
4) Introduction:
-- Ever since their discovery ... → Since their discovery …
-- The Gamma Ray Astronomy at PeV EnergieS - phase 3 (GRAPES-3) is such a detector array. → Delete the “a” and put the sentence with the above paragraph in a period
5) In section two, rephrase the next sentence so that it is better written in scientific English:
Located at an altitude of 2200 m above mean sea level in Ooty, Tamil Nadu, India (11.4◦N, 76.7◦E), GRAPES-3 consists of an array of 400 plastic scintillator detector modules spread over 25000 m2 G3SD [2] as well as a large area (560 m2 ) tracking muon telescope -G3MT [3].
Here a suggestion:
GRAPES-3 is located at an altitude of 2200 m above mean sea level in Ooty, Tamil Nadu, India (11.4◦N, 76.7◦E) and consists of an array of 400 plastic scintillator detector modules on 25000 m2 G3SD [2] and a large area (560 m2 ) tracking muon telescope -G3MT [3].
3) In section 3.1 the sentences:
-- The simultaneous occurrence of the burst in all nine directions suggests its origin close to Earth,
and
-- This line of inquiry holds clues for a better understanding and predictive power of solar superstorms that could cripple modern technological infrastructure on Earth and endanger the lives of the astronauts in space.

4) In the acknowledgements, the sentence “The authors also express sincere thanks to the ..." must be rephrased due to the plagiarism detection of this work:

5) In section 5, delete the discussion and leave only the conclusion. If the word discussion is keeping, add discussion. The discussion needs to be longer and the conclusions more concise. If the section is only for conclusions, I suggest a general conclusion and a listing (in item) of other conclusions for the science described in the paper. Some specific conclusions and a general one about the success and effectiveness of Grapes-3 as an experiment
